Answer:

Step 1: Make x the subject by moving all x terms to one side;

a)  4x-2x=7+3

Step 2; solve the linear equation

2x=10

x=10/2

x = 5

b) 2x-7x = -14-6

-5x = -20

x = -20/-5

x= 4

Hope this helps :) ! I'd apreciate if you'd mark my answer brainliest because ive been on the same rank for quite a loong time :(

A) 4x-3=2x+7

Let's say x is 5

4x5-3 = 2x5+7

20-3 = 10+7

17=17

So x is 5

B) 2x+6 =7x -14

Let's say x is 4

2x4+6 = 7x4-14

8+6= 28-14

14=14

So x is 4

A cube measures 3.0 CM on each side and has a mass of 25g. What is the density?
Oxana [17]

Answer:

D ≈ 0.925926 g/cm³

Step-by-step explanation:

Density = Mass / Volume

Step 1: Define

M = 25 g

V = (3 cm)³ = 27 cm³

D = ?

Step 2: Substitute and Evaluate for Density

D = 25g / 27 cm³

D = 25/27 g/cm³

D ≈ 0.925926 g/cm³

Which transformations have been performed on the graph of f(x) =<img src="https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D" id="Tex
Nookie1986 [14]

Answer:

(B) compress the graph closer to the x-axis

(E) translate the graph to the left

(F) translate the graph up

Step-by-step explanation:

When functions are transformed there are a few simple rules:

  • Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
  • Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
  • Multiplying the function by a number less than 1 compresses it towards the x-axis.
  • Multiplying the function by a number greater than 1 stretches it away from the x-axis.

This graph has been multiplied by 1/4 which is less than 1. It will be compressed.

This graph has x added to by 3. It will shift left 3 units.

This graph has the output outside of x added to by 6. It will shift 6 units up. See picture below. The original function is red. The new function is blue.

A mixture of green paint requires 3/4 pint yellow paint and 2/5 pint blue paint. How many pints of yellow paint will be needed i
katrin2010 [14]

Answer:

1\frac{7}{8}

Step-by-step explanation:

Given:

A mixture of green paint requires 3/4 pint yellow paint and 2/5 pint blue paint.

Question asked:

How many pints of yellow paint will be needed if the mixture contains one pint of blue paint ?

Solution:

We will easily find quantity of yellow paint, will be needed in the mixture, contains one pint of blue paint by using unitary method:

By using \frac{2}{5} \ pint blue paint, yellow paint requires = \frac{3}{4} \ pint

By using 1 pint blue paint, yellow paint requires = \frac{3}{4} \div\frac{2}{5} \\

                                                                               =\frac{3}{4} \times\frac{5}{2} \\\\ =\frac{15}{8} \\\\ =1\frac{7}{8} \ pint

Thus, 1\frac{7}{8} pint yellow paint requires in the mixture with one pint of blue paint.
