2+3=5

5x=y

25 is the only number between 20 and 30 divisible by 5

5x=25

x=5

5*2= 10

There are 10 boys

5*3= 15

There are 15 girls

There are 25 total members

A punch recipe requires 4/5 of a cup of pineapple juice for every 2 1/2 cups of soda. What is the unit rate of soda to pineapple

Varvara68 [4.7K]

We know that
2 1/2----------> (2*2+1)/2-----------> 5/2

[unit rate of soda to pineapple juice]=[quantity of soda]/[quantity of pineapple]
[unit rate of soda to pineapple juice]=[5/2]/[4/5]----> 25/8-------> 3.125---> 3 1/8

the answer is 3.125 (3 1/8)

Solve by Substitution:<br><br> 3x - y = 4<br> y = 6 - 2x

atroni [7]

Substitute 6 - 2x for y in the first equation

3x - (6 - 2x) = 4

5x - 6 = 4

5x = 10

x = 2

Plug 5 for x in either equations (I'll use the second equation)

y = 6 - 2 * 2

y = 6 - 4

y = 2

(2,2) is the solution.

Solve the equation for x by combining like terms first. <br> 3x-10+5x=2x-13

diamong [38]

Step-by-step explanation:

$\tt{3x - 10 + 5x = 2x - 13}$

Combine like terms on left hand side. Like terms are those which have the same base. Only coefficients of like terms can be added or subtracted.

⟼ $\tt{3x + 5x - 10 = 2x - 13}$

⟼ $\tt{8x - 10 = 2x - 13}$

Transpose 2x to left hand side and change it's sign.

Similarly , Transpose 10 to right hand side and change it's sign.

⟼ $\tt{8x - 2x = - 13 + 10}$

⟼ $\tt{6x = - 3}$

Divide both sides by 6

⟼ $\tt{ \frac{6x}{6} = - \frac{3}{6}}$

⟼ $\tt{x = - \frac{1}{2}}$

$\red{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt {x = - \frac{1}{2}}}}}}} }$

Hope I helped ! ♡

Have a wonderful day / night ! ㋡
