Rewrite each fraction with a denominator of 10 7/2 3/5

Vaselesa [24]

Answer:

$\frac{7}{2}=\frac{35}{10}$

$\frac{3}{5}=\frac{6}{10}$

Step-by-step explanation:

Given the fraction

$\frac{7}{2}$

Multiplying numerator and denominator by 5

$\frac{7}{2}\times \frac{5}{5}$

$=\frac{35}{10}$

Therefore,

$\frac{7}{2}=\frac{35}{10}$

Similarly,

Given the fraction

$\frac{3}{5}$

Multiplying numerator and denominator by 2

$\:\frac{3}{5}\times \:\frac{2}{2}$

$\frac{3}{5}\times \:\frac{2}{2}=\frac{6}{10}$

Therefore,

$\frac{3}{5}=\frac{6}{10}$

Hey!

Okay, to solve this problem, we'd first have to multiply both sides by two. The reason we do this is to get $y$ on its own.

Original Equation : 
$\frac{y}{2}$ < $-3$

New Equation {Changed by Multiplying 2 on Both Sides} :
$\frac{2y}{2}$ < $2$ ( $-3$ )

And we simplify the equation to get our answer.

Old Equation :
$\frac{2y}{2}$ < $2$ ( $-3$ )

New Equation {Changed by Simplification} :
y < -6

So, the equation $\frac{y}{2}$ < -3 simplified is y < -6.

Hope this helps!

Can you help me with this question?-8(-4x-1)-9x

Contact [7]

First you have to multiply -8 to (-4x-1)
which is, -12x+8
then there is -9x you have to add like terms
-12x-9x+8
-21x+8 is your final answer

The history museum is hosting a special exhibition on history of flight. The admission ticket for each adult costs $7 and the ad

stiks02 [169]

Answer:

Use simultaneous equation for this problem

y= number of adults

x = number of children

3y + 2x = 160

y + x = 60

then we double the second equation

3y + 2x = 160

2y + 2x = 120

we cancel x by elimination

3y - 2y = 160 - 120

y = 40

Step-by-step explanation:
