2x - 10 -12x + 6 = 6
-10x -4 = 6
-10x = 10
-x = 1
x = -1
Answer:
4 apples are $2.40
That means that 2 apples will be $1.20
And that one apple will be $0.60
$0.60*9= $5.40
She buys 5 more apples each week so she will buy 14 apples this week
$0.60*14= $8.40
Final answer : She will buy 14 apples next week for $8.40
Hope it helped! : )
Answer:
11.6 ft²
Step-by-step explanation:
We assume the 1/8 scale factor is the ratio of the linear dimensions of the smaller of the prisms to the larger. The ratio of areas will be the square of the ratio of the linear dimensions.
__
The ratio of areas will be ...
smaller area / larger area = (scale factor)²
smaller area = (larger area)×(scale factor)² . . . multiply by the denominator
smaller area = (740 ft²) × (1/8)² = 11.5625 ft² . . . use given values
The surface area of the smaller prism is about 11.6 square feet.
A-b=8
2a+3b=51
2a-2b=16
2a+3b=51
Subtract both
-5b=-35
b is 7 and a is 15
If two line segments intersect at 90 degrees, then two line segments are perpendicular.
