Express x as the subject of the formula​

Mathematics
1 answer:
Slav-nsk [51]3 years ago
5 0

Answer:

(a).y=5z+x

this isn't a problem, just flip x to the other side

so x = 5z-y

(b). b=x/2a

cross multiply

x = b×2a

x= 2ab

c.8d=cx

divide both sides by c

8d/c=cx/c

x=8d/c

d.3px=12q

divide both sides by 3p

3px/3p=12q/3p

x=12p/3q

e. 4x=m/3-n

cross multiply

4x × 3 = m-n

12x = m-n

divide both sides by 12

12x/12=m-n/12

x = m-n/12

lutik1710 [3]

Answer:

127 hamburgers

Step-by-step explanation:

let c = # of cheeseburgers

let h = # of hamburgers

c = 2h (The number of cheeseburgers sold was two times the number

of hamburgers sold.)

h + c = 381 (combined total)

h + 2h = 381

3h = 381

h = 127

Solve by factoring. p⁴=-25p²​
3241004551 [841]

Answer:

p=5i

Step-by-step explanation:

(p^(4)=-25p^(2))/p^(2)

p^(2)=-25

Square root both sides

p=5i

i is the square root of -1, so 5i is five times that much.

The square root of a negative number in not real. That is why it is i, and not a number.

What is the measure of LXZW?<br> 850<br> 150°<br> Y<br> 65°<br> 95<br> Z<br> 215°<br> W<br> 30°
Semenov [28]

Answer:

so the answer is 95°

Step-by-step explanation:

The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°. Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.
