Answer:
Step-by-step explanation:
Equation
2(x + 4) = x - 1
Solution
2x + 8 = x - 1 Subtract x from both sides
2x-x + 8 = - 1 Combine the left
x + 8 = - 1 Subtract 8 from both sides
x + 8-8 = - 1-8
x = - 9
Check
<em>LHS</em>
2(-9 + 4)
2(- 5)
-10
<em>RHS</em>
-9 - 1
- 10
It is going to be over 13 quarts.
∠1 and ∠2 are complementary.
∠1 + ∠2 = 90°
Question a:
∠1 = 23°
∠2 = 90 - 23 = 67°
Ans: 67°
Question b:
∠1 = x
∠2 = 2x + 3
x + 2x + 3 = 90
3x + 3 = 90
3x = 90 - 3
3x = 87
x = 29
∠1 = 29°
∠2 = 2(29) + 3 = 61°
Ans: ∠1 = 29°, ∠2 = 61°
9. You shouldn't agree, because they are equal to one another.
10. 84 cents plus 61 should be $1.45 because 84 + 61 is 145 and 100 cents equals 1 dollar, and then you have 45 left over.
100 - .63 is .37 because the whole painting is equal to 1, or .1, or in this case I used it as 100. The drawing is up to you, but you can just draw a canvas and shade in a little bit more than half but not the full canvas. .37 of the canvas is left.
