Answer:
2x+3=-13
x=5
Step-by-step explanation:
it says 2 times a number which would be the 2x, and it says the sum of that and 3 which would be 2x+3 and it says is 13. 2x+3=13
now solving it
2x+3=13
subtract 3 from both sides
2x=10
and divide 2 from both sides
x=5
Answer:
D
Step-by-step explanation:
Using sine rule
a/sin A =b/sin B
8/sin90° = x/sin60°
8 * sin60° = x
x =
Answer:
$8.40
Step-by-step explanation:
We can write a proportion to find the total amount last year using the information given. A proportion is two equivalent ratios set equal to each other.
We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
125(y)=100(10.50)
125y=1050
y=8.40
Divide the length of the wall by 2 to find the center of the wall:14/2 = 7 feet
The center of the painting is 2/2 = 1 foot.
The edge of the wall would be the center of the wall minus the center of the painting:
7 - 1 = 6 feet.
There should be 6 feet on each side of the painting.
