ALGEBRA 1. 5n + 34 = -2(1 - 7n) 2. 2(4x-3)=2(6+x)
4=n x=6

3. 3n − 5 = −8(6 + 5n) 4. -7(x - 6) = -6(x - 6)
n=-1 x=0

5. 2(-3a + 5) = -4(a + 4) 6. 4(2x - 3) = 5(3 + x)

7. -5(1 - 5x) = -5(-8x - 2)

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
