-7= z/-6 what does z equal

Mathematics
1 answer:
harina [27]2 years ago
7 0

Given:

- 7 =  \frac{z}{ - 6}

Taking -6 to the left side, we get in multiplication,

=  >  - 7 \times  - 6 = z

Now directly multiply and neglect the minus sign, as in multiplication, -sign \times -sign =  +sign

=  > 42 = z

So, value of z is <u>42</u>

So far, a storm has traveled 35 miles in 1/2 hour. If it is currently 5:00 P.M. and the storm is 105 miles away from you, at wha
SVEN [57.7K]

Answer: 6:30 P.M.

Step-by-step explanation:

We have the following data:

d=35 mi is the distance the storm travels

t=\frac{1}{2} h=0.5 h is the time it takes to the storm travel the 35 miles

D=105 mi is the distance between you and the storm

So, we can solve this with the following formula:

V=\frac{d}{t} (1)

Where V is the speed of the storm

V=\frac{35 mi}{0.5 h}

V=70 mi/h (2)

Now that we know the spped of the storm, we have to calculate the time T it takes to reach you, taking into account you are 105 miles away:

T=\frac{D}{V} (3)

T=\frac{105 mi}{70 mi/h} (4)

T=1.5 h (5)

If we add this 1.5 hours to your current time 5:00 P.M. we will have as a result the storm will reach you at 6:30 P.M.

Evaluate a(4b + c2) if a = 2, b = 5, and c = 1.
Maksim231197 [3]

Answer:

42

Step-by-step explanation:

a = 2, b = 5, and c = 1

  • a*(4b + c²) =               ⇒ plug in values
  • 2*(4*5 + 1²) =              ⇒ solving exponents
  • 2*(20 + 1) =                 ⇒ parenthesis
  • 2*21 =                         ⇒ multiplication
  • 42                               ⇒ answer
