alright so you need to find the unit rate for both of these bought items.


5.25(5 1/4) pounds is equal to $2.10 if you set it into an equation

5.25x = $2.10

x represents how much is the price for one pound of banana

to find x you divide $2.10 by 5.25

you can either plug that into a calculator (.4 is the answer)

to divide a fraction

2.10 / 1 ÷ 21/4

switch the 21/4


2.10/1 ÷ 4/21

instead of using division to solve this you actually multiply!(don't ask me why)

2.10 × 4 = 8.4

21 × 1 = 21

now divide 8.4 by 21 = $0.4 for each pound of bananas


do the same on the other persons payment

3.25x = 6.5

x = 0.5


now you answer it. which one is cheaper?

crystal is picking blueberries.so far,she has filled 2/3 of her basket,and the blueberries weigh 3/4pound .the equation 2/3w=3/4
vesna_86 [32]
In order to do this, we multiply both sides be the amount that would make the left side equal to 1.  This number is the reciprocal of the fraction, so we multiply both sides by 3/2.  This is equal to:

w = 9/8

So, the blueberries in crystal's basket will weigh 9/8 pounds when it is full.

What is x+y=10;y=x+10
Alenkasestr [34]

[ Answer ]

\boxed{\bold{X \ = \ 0, \ Y \ = \ 10}}

[ Explanation ]

  • System Of Equations \bold{\left \{ {X \ + \ Y \ = \ 10} \atop {Y \ + \ X \ = \ 10}} \right.}

-----------------------------------

  • [Substitute] Y = X + 10

\bold{\begin{bmatrix}x+x+10=10\end{bmatrix}}

  • Isolate x for x + x + 10 = 10: x = 0

For y = 10

Substitute x = 0

Y = 0 + 10

0 + 10 = 10

y = 10

  • Solutions

X = 0

Y = 10

\boxed{\bold{[] \ Eclipsed \ []}}

Hello, this is math and I need help ❤️ pls and ty ONLY SERIOUS ANSWERS
Greeley [361]

The bicycle with a 30-inches diameter rolls approximately 28.8 more than a tire with the diameter with 21-inches.

<u><em>How to solve:</em></u>

  • First use the formula: C = 3.14d
  • Replace the d value with 30 and solve the equation:

C = 3.14 x 30    ⇒   94.2477796077

  • Then solve the equation again but 21 as the d value:

C = 3.14 x 21     ⇒   65.9734457254

  • Then subtract 65.9734457254 from 94.2477796077 to get the approx. answer of 28.8
