If 1/4x=5-1/2 y what is the value of 8x-1

Mathematics
1 answer:
Alex73 [517]3 years ago
3 0

Answer:

<u>8x - 1 = 159 - 16y</u>

Step-by-step explanation:

1/4x=5-1/2 y what is the value of 8x-1

Beginning from the given equation, we will find the required

Which mean, we will transform the left hand side (1/4 x) to (8x-1)

\frac{1}{4} x=5-\frac{1}{2} y   multiply both sides by 4

∴ x = 20 - 2y

multiply both sides by 8

∴ 8x = 8 * ( 20 - 2y)

∴ 8x = 160 - 16y

Subtract 1 from both sides

8x - 1 = 160 - 16y - 1

∴ 8x - 1 = 159 - 16y

<u>So, the value of 8x - 1 = 159 - 16y</u>

Question 1 of 10 Jerry drew AJKL and AMNP so that K = ZN, ZLE ZP, JK = 6, and MN = 18. Are AJKL and AMNP similar? If so, identif
butalik [34]

Answer:

This is the answer I got

Step-by-step explanation:

JK / KL = MN / NP 6 / 4 = 18 / 12

Now u cross multiply. if both numbers are equal, they are similar. In this case, they are similar. 6 x 12 = 4 x 18

72 = 72

though the two corresponding sides of the triangles mentioned are proportional (proportionality being 1:3 ) but they need not be similar

for similarity either the third corresponding sides must be proportional or the included angle between the two proportional sides must be equal

Which equation shows y=−1/2x+4 is in standard form?
adelina 88 [10]

Answer:

B. x + 2y = 8 is your answer.

Step-by-step explanation:

So this is what you do:

y = -1/2x + 4 <u>You are going to add -1/2 to the other side.</u>

y + 1/2x = 4 <u>You are going to multiply the equation by 2.\</u>

B. x + 2y = 8 is your answer.
