You will need to know how much each lunch cost
so
9.40  <span>÷ 4  =  2.35
so each  lunch cost 2.35 dollars

now we need to find out how much it will cost for 10 lunches

10 x 2.35 = 23.5

so for 10 lunches it will cost 23.5</span>

We have an equation: 4/10= 9.40/?

Cross multiply:
4*? = 9.40*10
⇒ ?= 9.40*10/4= 23.5

10 students would spend $23.50 on the same school lunch~

Jackson had 1, 3/8 kg of fertilizer he used some to fertilize a flower bdd and he only had 2/3kg left how much fertilizer was us
ddd [48]

Answer:

Jackson had 1, ⅜ kg of fertilizer he used some to fertilize a flower bed and he only had ⅔ kg left how much fertilizer was used in the flower bed

Step-by-step explanation:

The calculator performs basic and advanced operations with fractions, expressions with fractions combined with integers, decimals, and mixed numbers. It also shows detailed step-by-step information about the fraction calculation procedure. Solve problems with two, three, or more fractions and numbers in one expression.

1/3 * (1/2 - 3 3/8) = -23/

24

≅ -0.9583333

Spelled result in words is minus twenty-three twenty-fourths.

How do you solve fractions step by step?

Conversion a mixed number 3 3/

8

to a improper fraction: 3 3/8 = 3 3/

8

= 3 · 8 + 3/

8

= 24 + 3/

8

= 27/

8

To find new numerator:

a) Multiply the whole number 3 by the denominator 8. Whole number 3 equally 3 * 8/

8

= 24/

8

b) Add the answer from previous step 24 to the numerator 3. New numerator is 24 + 3 = 27

c) Write a previous answer (new numerator 27) over the denominator 8.

Three and three eighths is twenty-seven eighths

Subtract: 1/

2

- 27/

8

= 1 · 4/

2 · 4

- 27/

8

= 4/

8

- 27/

8

= 4 - 27/

8

= -23/

8

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 8) = 8. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 8 = 16. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - one half minus twenty-seven eighths = minus twenty-three eighths.

Multiple: 1/

3

* the result of step No. 2 = 1/

3

* (-23/

8

) = 1 · (-23)/

3 · 8

= -23/

24

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-23, 24) = 1. In the next intermediate step the fraction result cannot be further simplified by canceling.

In words - one third multiplied by minus twenty-three eighths = minus twenty-three twenty-fourths

Write a two colon proof for each
Sladkaya [172]

We use the SSS congruence rule to prove the triangles to be congruent. From there, we then use CPCTC to show that angle I is congruent to angle L.

This is shown in the two column table (attached image below)

-----------

Notes:

SSS = side side side

CPCTC = corresponding parts of congruent triangles are congruent

<h2>angle in triangle</h2>

because the triangle above is an isosceles triangle, then both angles are of the same value.

and one thing you should know, the angle above shows the straight angle.

<em>so the sum of all angles is 180</em><em>°</em>

<u>can be written like </u><u>this</u><u> </u><u>:</u>

(5x+13)°+(3x+7)°=180°

5x + 13 + 3x + 7 = 180

8x + 20 = 180

8x = 180 - 20

8x = 160

x = 20

<em>(*the third choice is correct)</em>
