2x+5y=3
3x-2y=14
Answer:
x=−5/2 y+ 3/2
Step-by-step explanation:
Let's solve for x.
2x+5y=3
Step 1: Add -5y to both sides.
2x+5y+−5y=3+−5y
2x=−5y+3
Step 2: Divide both sides by 2.

You roll a 6-sided die.
What is P(not odd)?
Write your answer as a percentage.
Answer:
[tex]\boxed{\textsf{ Hence the percentage probability of getting a not odd is \textbf{ 50\% }.}}[/tex]
Step-by-step explanation:
Given that we roll a 6 sided dice . We need to find the probability that the outcome is not a odd number . So , when we roll a dice then the possible outcomes are ,
[tex]\sf\implies Sample\ space = \{ 1,2,3,4,5,6 \}[/tex]
And the total number of possible outcomes is 6 . That is ,
[tex]\sf\implies n(Sample \ space )= 6 [/tex]
Now the total number of non odd numbers that is even numbers is 3 ( 2 , 4 & 6) .
[tex]\sf\implies n(Outcomes_{(even)})= 3 [/tex]
Now , lets use the formula of Probability that is ,
Probability :-
[tex]\qquad\boxed{\boxed{\sf P = \dfrac{Total \ number \ of \ favourable\ outcomes }{Total \ number \ of \ possible\ outcomes }}}[/tex]
Now put on the respective values :-
[tex]\sf\implies P( getting\ a \ not \ odd ) = \dfrac{Total \ number \ of \ favourable\ outcomes }{Total \ number \ of \ possible\ outcomes } \\\\\sf\implies P( getting\ a \ not \ odd ) =\dfrac{3}{6} \\\\\sf\implies \boxed{\sf P( getting\ a \ not \ odd ) = \dfrac{1}{2} }[/tex]
[tex]\rule{200}2[/tex]
Expressing the probability as percentage :-
[tex]\sf\implies \% \ of \ getting \ non \ odd = Probability \times 100 \\\\\sf\implies \% \ of \ getting \ non \ odd = \dfrac{1}{2}\times 100 \\\\\sf\implies \boxed{\pink{\frak{ \% \ of \ getting \ non \ odd = 50\%}}}[/tex]

Solve the following system of equations.
x-3y=17
x+7y=-23
x=
y=
Answer:
-4y=40
y=-10
x-3(-10)=17
x-30=17
x=17+30
x=47
Step-by-step explanation:
Answer:
x= 5
y= -4
Step-by-step explanation:
x= 17+3y so you substitute what you got for x in so
17 +3y +7y = -23
10y=-40
y=-4 now you put -4 in for y in the first equation
x = 17 + (3 times -4)
x = 17 - 12
x=5

Evaluate acb−(a+d) if a=−2 , b=3 , c=−12 , and d=−4 .
Answer:
78Explanation:
acb − (a + d)
a = -2b = 3c = -12d = -4= (-2) (-12) (3) - (-2 + -4)
Parenthesis: (-2 + -4) = -6
= (-2) (-12) (3) - (-6)
Simplify (-2) (-12) (3): 72
72 - (-6)
78if a=−2 , b=3 , c=−12 , and d=−4 for expression acb−(a+d) then its value is 78.
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is acb−(a+d)
a times c times b minus a plus d
The values of a, b, c and d are given.
In the given expression a,b,c and d are variables and plus and minus are operators
a=−2 , b=3 , c=−12 , and d=−4 .
Substitute these values in expression acb−(a+d)
(-2)(-12)(3)-(-2+(-4))
When minus is multiplied two times we get positive, if three times we get negative
72-(-2-4)
72-(-6)
Seventy two plus six
72+6
Seventy eight
78
Hence if a=−2 , b=3 , c=−12 , and d=−4 for expression acb−(a+d) then its value is 78.

To go to the park, It costs $4 plus $3 per child. Which equation shows this situation
where x represents the number of children
Answer:
y = 3x + 4
Step-by-step explanation:
Because $4 is your base pay, it is your y-intercept. And because it is $3 per child, then that is your slope. "x" represents how many objects/people/etc. there could be.
Please help me ASAPPPPPP
Answer:
Step-by-step explanation:
4). Surface area of front and back = 2(lengh × height)
= 2(7×3)
= 63 cm²
Surface area of top and bottom = 2(length × width)
= 2(8×7)
= 112 cm²
Surface area of left and right = 2(width × height)
= 2(8×3)
= 48 cm²
Total surface area = 63 + 112 + 48
= 223 cm²
5). Surface area of top and bottom = 2πr²
= 2π(4)²
= 32π
= 100.53 cm²
Surface area of middle = h(π × d)
= 4(π × 8)
= 32π
= 100.53 cm²
Total surface area = 32π + 32π
= 64π
= 201.06 cm²
6). Surface area of front and back = [tex]2[\frac{1}{2}(\text{Base})(\text{Height)}][/tex]
= Base × Height
= 6 × 8
= 48 cm²
Surface area of bottom = 6 × 11
= 66 cm²
Surface area of the left = 8 × 11
= 88 cm²
Surface area of right = 10 × 11
= 110 cm²
Total surface area = 48 + 66 + 88 + 110
= 312 cm²
How can i identify a slope
Answer:
Rise over Run.
Step-by-step explanation:
If it's on a line on a graph you count how many it goes up until it's aligned with the next point and then you count how ever many over until it hits it. So it could be 2 up and 4 over making the slope 2/4.

Hillside orchard grows Fiji apples and Gala apples. There are 160 Fiji apple trees and 120 Galla apple trees in the orchard. Hillsides Orchers owners decide to plant 30 new gala apple trees. find the number of new Fiji apple trees the owner should plant if they want to maintain the same ratio of Fiji apple trees to gala apple trees
The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.
RatioRatio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
The ratio of Fiji apple to Gala apple = 160 : 120 = 4 : 3
If 30 new gala trees are planted, hence the number of gala trees increases to 150 (120 + 30). To maintain the same ratio:
Number of fiji apple = (4/3) * 150 = 200
New Fiji apple trees = 200 - 160 = 40
The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.

A new homeowner needs to determine the length of his rectangular backyard before he goes to the store for fencing. He knows that the area of
the yard is 51 square meters and that the width is 5.2 meters longer than the length. Which equation could be solved to determine the
dimensions of the backyard, where the length is / and the width is w?
0=w/2+5.2w -51
0=/2+5.2/-51
4w +10.451
4/+10.4 = 51
Answer:
0=w^2-5.2w-51
Step-by-step explanation:
51=width x length
length=width-5.2
substitute for length
51=width x (width-5.2)
51=w^2-5.2w
0=w^2-5.2w-51

Answer:
Step-by-step explanation:
Question (1)
x² + 10x + 12
= x² + 2(5x) + 5² - 5² + 12
= [x² + 2(5x) + 5²] - 5² + 12
= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]
= (x + 5)² - 13
Question (2)
y² - 6y - 15
= y² - 2(3y) - 15
= y² - 2(3y) + 3² - 3² - 15
= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]
= (y - 3)² - 3²- 15
= (y - 3)² - 9 - 15
= (y - 3)² - 24

Answer:
only Katie is right
Step-by-step explanation:
first, find the nth rule using the equation n = a + (n - 1)d
a = first term (here, it's 22)
n = the position of a term
d = the constant difference between each term (here, it's -5 since each term reduces by 5)
put these in and then simplify:
n = a + (n - 1)d
n = 22 + (n - 1)(-5)
n = 22 - 5n + 5
n = -5n + 27
this can be rewritten as n = 27 - 5n, which means therefore that only Katie is right. hope this helps!
Answer: Only Katie
Reason: Only Katie is correct!
