Answer:
In option a, w < 10
in option b, w = 10 and 2(20) + 2(10) = 40 + 20 = 60 < 150
in option c, w > 10 but 2(60) + 2(20) = 120 + 40 = 160 > 150
In option d, w > 10 but 2(55) + 2(30) = 110 + 60 = 170 > 150
Therefore the corect answer is option b.

Explanation:
3x _> 3
x _> 3/3
x _> 1
9x > 54
x > 6
We can write x like this:
1 <_ x < 6
Meaning that x is bigger or equal to 1 but less than 6
Answer:
B
Step-by-step explanation:
p(x) = r(x) * s(x)
= (x + 5) *(-7) {Use distributive property}
= x * -7 + 5 * -7
= - 7x - 35
Answer:
Step-by-step explanation:
so S and Y are complementary...that means when added, they equal 90 degrees.
S + Y = 90
S = 4Y - 185
4Y - 185 + Y = 90
5Y - 185 = 90
5Y = 90 + 185
5Y = 275
Y = 275 / 5
Y = 55 <===== angle Y is 55
S + Y = 90
S + 55 = 90
S = 90 - 55
S = 35
