Answer:
6t - 3
Step-by-step explanation:
9t - 3t + 2
Combine like terms: 9t - 3t = 6t
so
9t - 3t + 2
= 6t - 3
Answer:
290 cm2
Step-by-step explanation:
Answer:
7a²/16
Step-by-step explanation:
Area of the triangle PTS
½ × a × a
a²/2
Length of PS:
sqrt(a² + a²)
asqrt(2)
Length of MS:
¼asqrt(2)
Triangles MCS and TPS are similar
With sides in the ratio:
¼asqrt(2) : a
sqrt(2)/4 : 1
Area of triangle SMC:
A/(a²/2) = [(sqrt(2)/4)]²
2A/a² = 1/8
A = a²/16
Area of PTMC
= a²/2 - a²/16
= 7a²/16
Answer:
$34.89
Step-by-step explanation:
Here, we want to calculate the price of the pair of shoes.
Let the price of the belt be $x, we know that the price of pair of shoes would be x-1.79
so adding;
x + x-1.79 = 71.57
2x = 71.57 + 1.79
2x = 73.36
x = 73.36/2
x = $36.68
The price of pair of shoes = x-1.79 = 36.68-1.79 = $34.89
