Answer:60?
Step-by-step explanation:
260%=2.6
156/2.6
I must assume that you meant <span>X^2-10x =7. If that is indeed the case, then:
</span>X^2-10x =7 => x^2 -10x + 25 - 25 = 7, so that (x-5)^2 = 32 (Add 25, then
subtract 25)
Then x-5 = plus or minus sqrt(16)sqrt(2) = 4sqrt(2).
Then x = 5 plus or minus 4 sqrt(2) (answers)
Answer:
5x19=95
Step-by-step explanation:
The Prime Factors and Pair Factors of 95 are 5 × 19 and (1, 95), (5, 19) respectively.
All Factors of 95: 1, 5, 19 and 95.
Negative Factors of 95: -1, -5, -19 and -95.
Prime Factors of 95: 5, 19.
Prime Factorization of 95: 51 × 191
Sum of Factors of 95: 120.
Given: m∠A + m∠B = 90° (Definition of Complementary Angles).
Given: m∠B = (5x + 8)°
A) m∠A = 180° + (5x + 8) is your answer choice:
Why it isn't the others:
B) m∠A = 90° - (5x + 8)
You are solving for complementary angles (90° in total when combined), so you subtract the measurement for B (5x + 8) to get A.
C) m∠A = 180° - 2(5x + 8)°
You double the complementary angle to solve for the supplementary. Essentially, just divide this answer by two to get the complementary angles.
D) m∠A = 82 - 5x
I was confused by this one, but essentially they just did one step of the isolating the variable, which was subtracting 8 from both sides. They did not finish isolating the variable however.
