25.00-1.29= 23.71
23.71/4.99= 4.75

Answer:
Reflection
Step-by-step explanation:
This transformation maps the triangle on the other side of the quadrant.
The size of the triangle did not change
and it was not rotated, because its position did not change
therefore
it underwent
a reflection
4m+2 (m-5)=26
4m+2m-10=26
6m-10=26
6m=36
M=6
a = amount (in oz) of solution A
b = amount of solution B
The scientist wants a mixture of 110 oz, so
a + b = 110
Solution A consists of 65% salt, so each ounce of solution A contributes 0.65 oz of salt; similarly, each ounce of B contributes 0.9 oz. The mixture is supposed to consist of 75% salt, which amounts to 0.75 * (110 oz) = 82.5 oz of salt. So
0.65 a + 0.9 b = 82.5
Solve for a and b:
b = 110 - a
0.65 a + 0.9 (110 - a) = 82.5
0.65 a + 99 - 0.9 a = 82.5
0.25 a = 16.5
a = 66 ==> b = 44
