Answer:

Step-by-step explanation:

(x + 200)20 = 200(10) + x(40)

20x + 4000 = 2000 + 40x

2000 = 20x

X = 100 mL

Answer:

6p =120

Step-by-step explanation:

well the p's are very close together in a sense that we are going to multiply instead of add because they the p's would have space in between

Solve the inequality if possible 4(3-2x)>2(6-4x)

GenaCL600 [577]

Final Answer: No Solution

Steps/Reasons/Explanation:

Question: $4(3- 2x) > 2(6- 4x)$

Step 1: Divide both sides by $2$ .

$2(3 - 2x) > 6 - 4x$

Step 2: Expand.

$6 - 4x > 6 - 4x$

Step 3: Since $6 - 4x > 6 - 4x$ is false, we have no solution.

VikaD [51]

Given :

Susan wanted to share her 37 seashells with her two younger brothers.

To Find :

If she divided her seashells between the three of them, how many would each person get.

Solution :

Let, each person will get x seashells.

So,

$x = \dfrac{\text{Total number of seashells}}{\text{Number of persons}}\\\\x = \dfrac{37}{3}\\\\x = 12.333$

But as we know seashells cannot be in decimal.

Therefore, each person will get exactly 12 shells.

The lateral area is the area of all the sides except the base. So you find the area of the triangles (16), then the left rectangle (80), then the right rectangle (90). Finally you add them together.
16+16+80+90=202
