Evaluate the expression below.
(8.1+7.9)x - (25 division 5)x

Evaluate The Expression Below.(8.1+7.9)x - (25 Division 5)x

Answers

Answer 1

Answer:

11x

Step-by-step explanation:

Start by simplifying the parentheses. (8.1+7.9)=16 and (25/5)=5. Next, distribute each x into the parentheses. You should now have 16x-5x. Since they share like terms, you can subtract them.

Find the measure of the missing angles.

Answers

Answer:

angles b and c should be 153° each.

Step-by-step explanation:

We know the smaller angle is 27°. The other small angle, vertical to the 27° angle is also 27° because they are vertical angles. Along the lines, two angles should form 180°. So 180-27=153°. All together the angles should be 360°. Check your answer by doing 153+153+27+27=360. therefore the missing angles are both 153°

which binomial is a factor of 8x^2y^3-18y

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

[tex]8x^2y^3-18y[/tex]

Apply exponent rule:   [tex]a^{b+c}=a^ba^c[/tex]

[tex]8x^2y^3-18y=8yy^2-18y[/tex]    ∵ [tex]x^2y^3=yy^2[/tex]

                    [tex]=4\cdot \:2yy^2+9\cdot \:2y[/tex]

Factor out common term 2y

                    [tex]=2y\left(4x^2y^2-9\right)[/tex]

We know that the Binomial is an expression that consists of two terms. Thus,

(4x²y²- 9) represents the binomial factor of [tex]8x^2y^3-18y[/tex]

We can further simplify by Factoring 4x²y² - 9:  (2xy + 3) (2xy - 3)

                      [tex]=2y\left(2xy+3\right)\left(2xy-3\right)[/tex]

Here:

(2xy + 3) and (2xy -3) are the binomial factors of [tex]8x^2y^3-18y[/tex] as each of them consists of two terms.

Triangle A is a scaled version of triangle B. The dimensions of triangle B are twice the dimensions of triangle A. The area of
triangle B is 144 sq cm.
What is the area of triangle A?

Answers

Answer:

576 sq cm

Step-by-step explanation:

For example imagine a rectangle, the area of which is width * height = area

If you multiply the dimensions by 2 you multiply the width AND the height which is 2 * width * 2 * height = 4 * width * height

This is true for all scalings, if you times the dimensions by n, you times the area by n^2

144 * 2^2 = 576

A man drove 250 miles in 2.5 hours. If the posted speed limit was 75 mph the entire way how many miles per hour over the speed limit was he going?
A. 10 mph
B. 50 mph
C. 25 mph
D. 78 mph

Answers

Answer:

C. 25 mph

Step-by-step explanation:

First, find his speed in miles per hour:

250/2.5

= 100

This means he was going 100 mph

To find how much he was going over, subtract 75 from this

100 - 75

= 25

So, he was going 25 mph over the speed limit

The correct answer is C, 25 mph
