Two-thirds a number plus 4 is 7

Mathematics
1 answer:
Mrac [35]3 years ago

<span>4.5
If you are told that two-thirds a number plus 4 is 7 and you wish to figure the number you can make an algebra formula: (2/3)X + 4 = 7
To simplify the formula you want to get the X alone. Begin by subtracting 4 from each side. (2/3)X + 4 - 4 = 7 - 4, so you now have (2/3)X = 3. To get the (2/3)X to be just 1X multiply each side by 3/2, so ((2/3)X)x(3/2) = 3x(3/2) giving you X=4.5</span>

Find the slope of the line that passes through the points (­-8, ­-3) and (2, 3)
Artyom0805 [142]

Answer:

c

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 8, - 3) and (x₂, y₂ ) = (2, 3)

m = \frac{3+3}{2+8} = \frac{6}{10} = \frac{3}{5} → c

The measures of three angles of a triangle are given by (8x - 5), (2x)º, and (3x – 10). What is the measure of the largest angle
zhannawk [14.2K]

Answer: 115°

Step-by-step explanation:

We should note that the sum of the angles that are in a triangle is equal to 180°, therefore we will add the angles given and equate them to 180°. This will be:

(8x - 5) + (2x) + (3x - 10) = 180

8x - 5 + 2x + 3x - 10 = 180

Collect like terms

8x + 2x + 3x = 180 + 5 + 10

13x = 195

x = 195/13

x = 15

The angles are:

8x - 5 = 8(15) - 5 = 120 - 5 = 115°

2x = 2(15) = 30°

3x - 10 = 3(15) - 10 = 45 - 10 = 35°

Therefore, the largest angle is 115°

Anika [276]

Answer:

£151.20

Step-by-step explanation:

20%= 100%divided by 5

To find 100% from 20% you x by 5

so you times 30.24 by 5

30.24x 5 = 151.2

So the answer is £151.20

interest percentage rate would be 1.6754%
