Step-by-step explanation:
What is the solution of 4+ 5x+66 = x+ 10? O x = -10 Ox=3 O x=-10 or x = 3 O no solution
Hey there!
4 + 5x + 66 = x + 10
70 + 5x = x + 10
5x + 70 = x + 10
SUBTRACT x to BOTH SIDES
5x + 70 - x = x + 10 - x
5x + 70 - 1x = 1x + 10 - 1x
SIMPLIFY IT!
4x + 70 = 10
SUBTRACT 70 to BOTH SIDES
4x + 70 - 70 = 10 - 70
SIMPLIFY IT!
4x = -60
DIVIDE 4 to BOTH SIDES
4x/4 = -60/4
SIMPLIFY IT!
x = -60/4
x = -15
Therefore, your answer is: x = -15
Good luck on your assignment & enjoy your day!

Answer:
x = -15Step-by-step explanation:
Given :
4 + 5x + 66 = x + 10#1 : Combine like terms on each side.
4 + 5x + 66 = x + 105x + 70 = x + 10#2 : Subtract x from each side.
5x + 70 - x = x + 10 - x4x + 70 = 10#3) Subtract 70 from each side.
4x + 70 - 70 = 10 - 704x = -60#4) Divide 4 from each side.
4x/4 = -60/4x = -15Solution : x = -15
Renee is buying Halloween candy. She wants to buy candy bars and lollipops and spend no more than $28. Each candy bar costs $0.45 and each lollipop costs $0.25. Which inequality represents the possible combinations of x, the number of candy bars, and y, the number of lollipops Renee can buy?
The inequality that represents the possible combinations of candy bars and lollipops that he can buy is given by:
[tex]0.45x + 0.25y \leq 28[/tex]
What is the inequality that models this situation?The total price can be no more than $28, hence:
[tex]T \leq 28[/tex]
Each candy bar costs $0.45 and each lollipop costs $0.25. x is the number of candy bars and y of lollipops. Hence, the total price is given by:
T = 0.45x + 0.25y.
Hence, the inequality that models the situation is:
[tex]0.45x + 0.25y \leq 28[/tex]

Answer:
1) D. 8 2/6 hotdogs
2) B. 2 1/5 cakes
Step-by-step explanation:
1) If she's dividing 50 hotdogs equally among 6 people, then you would divide 50 by 6 to find how many each person gets.
note: 50 ÷ 6 is the same as [tex]\frac{50}{6}[/tex].
[tex]\frac{50}{6}[/tex] = [tex]8\frac{2}{6}[/tex]
6 can go into fifty 8 times, so there is a whole number of 8. There is 2/6 left over, so the final result is [tex]8\frac{2}{6}[/tex].
2) If Sako makes 11 cakes and wants to share it equally among 5 people, we can divide 11 by 5 to find how many each person gets.
[tex]\frac{11}{5} =2\frac{1}{5}[/tex]
5 can go into eleven 2 times, so there is a whole number of 2. There is 1/5 leftover, so the final result is [tex]2\frac{1}{5}[/tex].
Hence, the answers are D, and B.

Step-by-step explanation:
Find the area of each polygon each square on the grid represents 1 square centimeter the answers are mixed up at the bottom of the page cross out the answers as you complete the problems
Answer:
Step-by-step explanation:
Area of composite shapes:
13) Figure 1:
Figure1 is a rectangle.
l = 4 cm & w = 2 cm
Area of figure1 = l * w
= 4 * 2
= 8 cm²
Figure2:
Figure2 is a parallelogram
base = b = 4 cm
h = 4 cm
Area of figure2 = b * h
= 4 * 4
= 16 cm²
Area of composite shape = 8 + 16
= 24 cm²
14) Figure1:
Figure 1 is a trapezium. a & b are parallel sides and h is the height
a = 4 cm ; b = 6 cm; h = 4 -2 = 2 cm
[tex]\sf Area \ of \ figure1 =\dfrac{(a+b)*h}{2}[/tex]
[tex]= \dfrac{(4 +6)*2}{2}\\\\= 10 \ cm^{2}[/tex]
Figure2:
Figure2 is rectangle. l = 6 cm ; w = 2 cm
Area of figure2 = 6*2
= 12 cm²
Area of composite shape = 10 + 12
= 22 cm²
15) Figure 1 & figure 2:
Figure 1 and figure 2 are congruent triangles
base = b = 3 cm & h= 4 cm
[tex]\sf area \ of \ figure1 \ and \ figure 2 = 2*\dfrac{1}{2}b*h[/tex]
= b *h
= 3 * 4
= 12 cm²
Figure3:
Figure 3 is a square.
side = 3 cm
Area of figure3 = side *side
= 3 * 3
= 9 cm²
Area of composite shape = 12 + 9
= 21 cm²
What is the 15th term of 8,32,128,…
Answer:
2147483648
Step-by-step explanation:
The pattern being used is x4.
8 x 4 = 32
32 x 4 = 128
128 x 4 = 512
512 x 4 = 2048
2048 x 4 = 8192
8192 x 4 = 32768
32768 x 4 = 131072
131072 x 4 = 524288
524288 x 4 = 2097152
2097152 x 4 = 8388608
8388608 x 4 = 33554432
33554432 x 4 = 134217728
134217728 x 4 = 536870912
536870912 x 4 = 2147483648

anthony scored 8 goals in the second round. this made his total score 39. how many points did he score in the first round
Answer:
He had 31 points in the first round.
Step-by-step explanation:
Answer:
39-8= 31
Step-by-step explanation:
let the first round be x
second round =8

Laura babysat 8 nights during the month of July. She earned $22, $30, $35, $25, $25, $20, and $27 for seven nights. How much did she earn the eighth time if the mean of the data is $26.50?
Answer:
$28
Step-by-step explanation:
Given:
data = [22,30,35,25,25,20,27]
For eight night, the new list is:
new_data = [22,30,35,25,25,20,27,x]
Mean = 26.50
Mean Formula:
[tex]\displaystyle \large{m=\dfrac{x_1+x_2+x_3+...+x_n}{n} }[/tex]
Therefore:
[tex]\displaystyle \large{26.50=\dfrac{22+30+35+25+25+20+27+x}{8}}[/tex]
Multiply both sides by 8:
[tex]\displaystyle \large{26.50\cdot 8=\dfrac{22+30+35+25+25+20+27+x}{8} \cdot 8}\\\displaystyle \large{212=22+30+35+25+25+20+27+x}[/tex]
Solve for x:
[tex]\displaystyle \large{212=22+30+35+25+25+20+27+x}\\\displaystyle \large{212=184+x}[/tex]
Subtract 184 both sides:
[tex]\displaystyle \large{212-184=184+x-184}\\\displaystyle \large{28=x}[/tex]
Therefore, she will earn $28 in eighth night
The attachment below is the result of combining all eighth data as we get 26.5 through python language with numpy package.
Answer: $28.
Step-by-step explanation: To solve this problem, we should first find the mean of the data with the seven payments that are given already:
22 + 30 + 35 + 25 + 25 + 20 + 27 = 184.
184 / 7 = 26.2857142857.
In order to figure out how much she made the eighth night with the mean of the data being $26.50, we can pick a number and add it to 184 (the total of the seven payments), and divide the total by 8. The number we can try is 28. The work is done below:
184 + 28 = 212.
212 / 8 = $26.50.
Therefore, Laura's payment on the eighth night was $28.
Hope this helps! :)

You have a coin and a bag of marbles. The bag of marbles has 5 marbles of each color: Red, yellow, blue and green. What is the probability of flipping a head and then selecting a blue marble?
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Since there are a total of 4 colors, and there are 5 of each colors, the total marbles in the bad would be;
5 x 4 = 20
If a color is selected at random the probability would be
[tex]\frac{part}{whole}[/tex]
our part is 5
our whole is 20
so the probability would be;
[tex]\frac{5}{20}[/tex] or [tex]\frac{1}{4}[/tex] when reduced

Sophie earned a grade of 72% on her multiple choice history final that had a total of 200 problems. How many problems on the final exam did Sophie get wrong?
Answer:
56 questions.
Step-by-step explanation:
percent got wrong = 100% - percent got correct.
percent got correct = 72%
percent got wrong = 100%-72% = 28% or 0.28
questions got wrong = total questions * percent got wrong.
total questions = 200
questions got wrong = 200*0.28 = 56 questions
Therefore, Sophie got 56 questions wrong.

Given g(x) = x² - 6x - 16, which statement is true?

How to analyze a second orden polynomial with constant coefficients
In this case we have a second order polynomial of the form x² - (r₁ + r₂) · x + r₁ · r₂, whose solution is (x - r₁) · (x - r₂) and where r₁ and r₂ are the roots of the polynomial, which can be real or complex numbers but never both according the fundamental theorem of algebra.
If we know that g(x) = x² - 6 · x - 16, then the factored form of the expression is g(x) = (x - 8) · (x + 2). Hence, the correct choice of this question with the given polynomial is "The zeros are -2 and 8, because the factors of g are (x + 2) and (x - 8)". [tex]\blacksquare[/tex]
