Add 5 to me.Then divide by 7.If you add 12 and the subtract 7,you get 10

qaws [65]

Answer: 30

Step-by-step explanation:

Let the number be y

Add 5 to me

Y+5............equ1

Divide by 7

Y+5/7

Add 12

Y+5/7+12

Subtract 7

(Y+5)/7+(12-7)=10

12-7=5

Substitute

(Y+5)/7+5=10

Find the lowest common multiple

((Y+5)+7(5))/7=10

(Y+5)+35)/7=10

Cross multiply

Y+5+35=70

Y+40=70

Y=70-40

Y=30

The unknown number is 30

Price-club sells a 12-ounce box of crackers for $2.59 and Shop Mart sells 1-1/2 pound box of crackers for $4.68. What is the uni

katen-ka-za [31]

Unit price would be the price per ounce.

Divide the total cost by the number of ounces:

Price Club : 2.59 / 12 = $0.216 per ounce

Shop Mart: 1-1/2 pounds = 1.5 x 16 = 24 ounces.

4.68 / 24 = $0.195 per ounce.

Draw a rectangular fraction model to explain your thinking. Then, write a multiplication sentence. A. 2 3 of = 3 5

myrzilka [38]

Answer:

$\frac{2}{3}\ of\ \frac{3}{5} = \frac{2}{5}$

Step-by-step explanation:

Given

$\frac{2}{3}\ of\ \frac{3}{5}$

Solving (a): Multiplication sentence

$\frac{2}{3}\ of\ \frac{3}{5}$

Rewrite of as *

$\frac{2}{3}\ of\ \frac{3}{5} = \frac{2}{3}\ *\ \frac{3}{5}$

Solve

$\frac{2}{3}\ of\ \frac{3}{5} = \frac{2}{5}$

Hence, the multiplication sentence is:

$\frac{2}{3}\ of\ \frac{3}{5} = \frac{2}{5}$

Solving (b): Rectangular fraction model

In (a) above, the result is 2/5

The fraction model will be represented as thus:

Draw a rectangle
Partition in to 5 equal parts (5 represents the denominator)
Shade 2 of the 5 partitions (2 represents the numerator)

Find what x is? 5×3>4+8+x a good help for your brain!

MaRussiya [10]

Answer:

x = 2.25 or any number greater

Step-by-step explanation:

5x3 > 4 + 8 + x

Make them equal to each other to get x

5x3 = 4 + 8 + x

(5x)(3) = 12 + x

- x - 3 - 3 - x

4x = 9

$\frac{4x}{4} = \frac{9}{4}$

x = 2.25

Once you get x plug it in to get the truth of the expression
