Answer:
x=-5 Hope this helped! Goodnight!
Step-by-step explanation:
Let's solve your equation step-by-step.
−3(2x+6)=12
Step 1: Simplify both sides of the equation.
−3(2x+6)=12
(−3)(2x)+(−3)(6)=12(Distribute)
−6x+−18=12
−6x−18=12
Step 2: Add 18 to both sides.
−6x−18+18=12+18
−6x=30
Step 3: Divide both sides by -6.
−6x /−6 = 30 /−6
x=-5
Answer:
x= -5

HELP!!! Last month, there were 4 sunny days for every rainy day. If there were 30 days in the month, how many days were rainy? Explain your reasoning. If you get stuck, consider using a tape diagram.
Answer:
6
Step-by-step explanation:
Based on the ratio of sunny days to rainy days last month, there would have been 6 rainy days.
For every 4 sunny days, there is 1 rainy day. This means that every 5 days, one of those days will be rainy and 4 will be sunny.
We can therefore represent that as:
= 1/5 of any number of days will be rainy
If there are 30 days therefore, 1/5 of those 30 days will be rainy:
= 1/5 x 30
= 6 days
In conclusion, 6 days will be rainy out of 30 days.

1 ≤ x + 7 < 7
explain how u got the answer plz
Answer:
-6 ≤ x < 0
Step-by-step explanation:
Subtract the 7 on both sides to get x isolated.
Answer:
-6 ≤ x < 0
Step-by-step explanation:
This is the answer because:
1) First, we have to isolate the x
2) In order to isolate the x, you have to subtract 7 from 1 and 7
1 - 7 = -6
7 - 7 = 0
Therefore, the inequality is -6 ≤ x < 0

question: What is the slope of the line?
Answer:
4/5
Step-by-step explanation:
If you look at the point (-2,0) you can see that it sits directly on the line above 2. If you also at the point (3,4) you can see that its also sitting directly in the middle, where the line runs through it. Using this information we can use Rise/Run.
Rise/Run = Y/X
from (-2, 0) you rise 4 and you run 5 to the right to land on (3,4).
This is one of many ways you can calculate The slope from a graph!

Let numerator of fraction be x and denominator be y.
∴ Fraction = x/y
★ Part - A :
[tex]:\implies\tt\:\dfrac{x\times 4}{y-2}=2[/tex]
[tex]:\implies\tt\:4x=2(y-2)[/tex]
[tex]:\implies\tt\:4x=2y-4[/tex]
[tex]:\implies\tt\:2y=4x+4[/tex]
[tex]:\implies\bf\:y=2x+2\:\:\dots (1)[/tex]
★ Part - B :

[tex]:\implies\tt\:7(x+15)=9(2y-2)[/tex]
[tex]:\implies\tt\:7x+105=18y-18[/tex]
From equation (1)...

[tex]:\implies\boxed{\bf{y=8}}[/tex]
∴ Fraction = x/y = 3/8
Hope It Helps!Answer: 3/8
Step-by-step explanation:
Let x represent the numerator and y represent the denominator.
Equation 1: (4x)/(y - 2) = 2
4x = 2(y - 2) Cross Multiplied
4x = 2y - 4 Distributed
4x - 2y = -4 Subtracted 2y from both sides
Equation 2: (x + 15)/(2y - 2) = 9/7
9(2y - 2) = 7(x+15) Cross Multiplied
18y - 18 = 7x + 105 Distributed
-7x + 18y - 18 = 105 Subtracted 7x from both sides
-7x + 18y = 123 Added 18 to both sides
Solve the system of equations using Elimination Method:
EQ1: 4x - 2y = -4 → 9(4x - 2y = -4) → 36x - 18y = -36
EQ2: -7x + 18y = 123 → 1(-7x + 18y = 123) → -7x + 18y = 123
29x = 87
÷29 ÷29
x = 3
Substitute x = 3 into either equation to solve for y:
EQ1: 4x - 2y = -4
4(3) - 2y = -4
12 - 2y = -4
-2y = -16
y = 8
The numerator (x) = 3
The denominator (y) = 8
The fraction is: 3/8

answers to unit 1 geometry basics homework 4 angle addition postulate
Answer:
EF = 58
Step-by-step explanation:
Find the diagram of the question attached.
According to the addition postulate;
DE+EF = DF
Given
DE = 47
EF = 3x+10
DF = 9x-39
Substitute into the addition postulate formula and get x
47+3x+10= 9x-39
Collect like terms
3x-9x = -39-10-47
-6x = -96
x = -96/-6
x = 16
Next is to evaluate EF:
EF = 3x+10
EF = 3(16)+10
EF = 48+10
EF = 58
Hence the measure of EF is 58

Equation
-18 = 10 + x → Change the x and 10, changing their sign to the opposite:
-x = 10 + 18 → Sum:
-x = 28 → Change the position of the minus sign:
x = -28

In ΔRST, the measure of ∠T=90°, the measure of ∠S=75°, and ST = 97 feet. Find the length of TR to the nearest tenth of a foot.
9514 1404 393
Answer:
TR = 362.0 ft
Step-by-step explanation:
The tangent relation is useful for this.
Tan = Opposite/Adjacent
tan(75°) = TR/ST = TR/(97 ft)
TR = (97 ft)(tan(75°))
TR ≈ 362.0 ft
Hudson and Knox are in a race. Hudson is running at a speed of 8.8 feet per second. Knox got a 30-foot head start and is running at a speed of 6.3 feet per second. How many seconds will it take until Hudson and Knox have run the same number of feet? Write the equation.
Answer:
It will take 12 seconds to be at same distance
The equation is;
8.8x = 6.3x + 30
Step-by-step explanation:
Let the number of seconds it will take be x
Mathematically, distance = speed * time
At x-seconds , Hudson will be at a distance of 8.8 * x = 8.8x ft
At x seconds , Knox will be at a distance of 30 ft + (6.3 * x) = 6.3x + 30feet
So the time it will take them to be at the same distance can be calculated using the equation;
6.3x + 30 = 8.8x
8.8x - 6.3x = 30
2.5x = 30
x = 30/2.5
x = 12 seconds
Answer:
Step-by-step explanation:
It will take 12 seconds to be at same distance
A certain species of fish costs $3.99 each. You can spend at most $45. How many of this type of fish can you buy for your aquarium?

Andrew is evaluating his current financial position by totaling his monthly cash inflows and outflows. His cash inflows each month are $60 in allowance and $240 in wages from his part-time job working at the pet store. His cash outflows each month are $170 for his car payment, $70 in entertainment, and $45 for gas and food. How much, if anything, does Andrew have left over each month?
Answer:
Andrew has $15 left over each month
Step-by-step explanation:
Inflows=$240+$60=$300/mo.
Outflows=$170+$70+45=$285/mo.
Inflows-Outflows=left over
$300-$285=$15
