What is the estimate of 872 times 3

1 answer:

8 0

To estimate the answer of 872*3 we know that 872 is only 28 away from 900 so we'll round 872 up to 900. Then we can take 900*3 which is 2,700. So we now know that 872*3 is roughly 2,700.

Hope this helps!=)

Solve the following equation algebraically show the steps: <br><br><br> n/3 -5 = 5

Lana71 [14]

$\longrightarrow{\green{ \: n = 30 }}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$\frac{n}{3} - 5 = 5$

➼ $\: \frac{n}{3} = 5 + 5$

➼ $\: \frac{n}{3} = 10$

➼ $\: n = 10 \times 3$

➼ $\: n = 30$

Therefore, the value of n is 30.

$\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}$

$\frac{30}{3} - 5 = 5$

✒ $\: 10 - 5 = 5$

✒ $\: 5 = 5$

✒ $\: L.H.S.=R. H. S$

Hence verified.

The cake store is having a 25\%25% off sale on all of its cakes. If the cake you want regularly costs \$9$9, how much would you

Ivanshal [37]

Answer:

You would save $2.25.

Step-by-step explanation:

In order to find discount on an item, you need to multiply the discount by the original amount of the item. In this case, the cake you want regularly costs $9. If the sale includes a 25% discount, then you need to first convert your percentage to a decimal by dividing by 100:

$\frac{25}{100} =0.25$

You can then take this amount multiplied by the original cost of the cake to get your discount:

0.25 x 9 = 2.25, so you would save $2.25 with the discount and pay only $6.75 for the cake you want.
