You can simply collect terms, subtract the constant and divide by the x-coefficient. It is generally considered easier to do those steps if you eliminate fractions first (multiply by 12).

Multiply by 12

... 4(x -1) +3(x +5) = 6

... 4x -4 +3x +15 = 6 . . . . . eliminate parentheses

... 7x +11 = 6 . . . . . . . . . . . .collect terms

... 7x = -5 . . . . . . . . . . . . . . subtract the constant 11

... x = -5/7 . . . . . . . . . . . . . divide by the x-coefficient

_ _ _ _ _ _ _

Here it is the other way.

... x(1/3 +1/4) +(-1/3 +5/4) = 1/2

... (7/12)x + 11/12 = 1/2 . . add the fractions to finish collecting terms

... x + 11/7 = 6/7 . . . . . . . multiply by 12/7

... x = -5/7 . . . . . . . . . . . subtract 11/7

At the third step here, you could subtract 11/12 before doing the multiply. You get the same answer, but you have to do the extra conversion of 1/2=6/12.

H=-t^2+95
The y intercept here is 95, and it represented from where the boy threw the ball.

If he threw it from 95 ft above the ground, the best answer for where he is is on a bridge.
His backyard is at 0 ft (sea level). An underground cave is below sea level. A ladder is probably not 95 ft.

Final answer: D

The perimeter of a rectangle is 24 in.and its length is 3times its width. What are the length and width of ThE rectangle?
Mama L [17]

let w = width and 3w = length

perimeter is the distance around the outside of the object or P = 2L + 2W

2(3w) + 2w = 24

6w + 2w= 24

8w = 24

w= 3

3w= 9

Width is 3in. and length is 9in.

Helllpppppppppp please someone.?????
Liula [17]

Answer:

(-5,5)

Step-by-step explanation:

Multiply the first equation by -2,and multiply the second equation by 1.

−2(x+5y=20)

1(2x−7y=−45)

Becomes:

−2x−10y=−40

2x−7y=−45

Add these equations to eliminate x:

−17y=−85

Then solve−17y=−85for y:

(Divide both sides by -17)

y=5

x+5y=20

Substitute  5 for y in x+5y=20:

x+(5)(5)=20

x+25=20(Simplify both sides of the equation)

x+25+−25=20+−25(Add -25 to both sides)

x=-5

Write a brief explanation on how to simplify radicals
MrMuchimi
2 ways: make a little divide tree based on how many times you can divide it. Like you have sqrt88 you know it can divide by 2. So its 2 and 44, and 44 can be broken to 2 and 22, then 2 and 11. 11 can’t be divided anymore.

Now choose numbers that are the same and pair them together. These go outside the radicand. You had three 2’s and one 11. So a 2 would go on the outside and the remaining 2 and 11 would be multiplied leaved 2sqrt22.

Another way is to divide by the highest squared number. Taking sqrt88 again. 4 would be the highest squared number. So 88 would be 4 and 22, then 2 and 11. Since you have a 4 which is a perfect square you put that squareroot outside. The inside would remain the same because it wouldn’t break down into perfect squares or pairs anymore. So that would be 2sqrt22.

A kitchen makes 2944 ounces of soup each week. There are 128 ounces in one gallon. How many gallons of soup does the kitchen mak
zhannawk [14.2K]
Step 1:
Find number of gallons in one week
Total oz ÷ oz per gallon= gallons
=2944/128
= 23 gallons in one week

Step 2:
Multiply gallons made in one week by two.
=23 gallons per week * 2
=46 gallons made in 2 weeks

Hope this helps! :)
