The area of a rectangle whose width is 5 units, and whose length is x.

Answer:

The solution for the system of equations is

x=2,y=−2

Explanation:

4x−3y=14.....equation (1)

y=−3x+4.....equation (2)

Solving by substitution

Substituting equation 2 in equation 1

4x−3⋅(−3x+4)=14

4x+9x−12=14

13x=14+12

13x=26

x=2

Finding y by substituting x in equation 1

4x−3y=14

4⋅2−3y=14

8−3y=14

8−14=3y

3y=−6

y=−2

Answer:X=−4x/3−21

Answer:

108 ft²

Step-by-step explanation:

Area of a rectangle = width × length

Area of a triangle = 1/2 × base × height

Surface area = rectange + rectangle + rectangle + 2 congruent triangles

                     = (3 × 8) + (4 × 8) + (5 × 8) + 2(1/2 ×3 × 4)

                     = 24 + 32 + 40 + 12

                     = 108 ft²

Answer:

Step-by-step explanation:

E + F + G = 180°

112 + (13x-7) + 4x = 180

112 + 13x - 7 +4x =180

17x + 105 = 180

17x = 180 - 105

17x = 75

x = 75/17

I guess it is 45°

Step-by-step explanation:

Hope it helps!!!!

Answer:

45°

Step-by-step explanation:

the sum of the exterior angles of a polygon is 360°

a regular octagon has 8 equal exterior angles , then

exterior angle = 360° ÷ 8 = 45°

Do 60 divided by 4 to get ur answer

Or you can multiply to get another answer too sense you probably need to get the full 100 percentage.

Answer:

When numbers become very small or large standard form (or standard index form) is used to make them manageable. In standard form or unit a number is written as:

[a number between 1 and 10] × [ an integer power of 10]

C. Ankur found that the quotient of a positive number and a negative number is positive

Step-by-step explanation:

Given the expression that is solved by Ankur as shown;

[tex]15 \frac{1}{3} \div(-4\frac{2}{3} )[/tex]

We were told that Ankur got 3. Let us evaluate to see ankurs error.

change to improper fraction first

[tex]= 15 \frac{1}{3} \div(-4\frac{2}{3} )\\= \frac{46}{3} \div \frac{-14}{3} \\= \frac{46}{3} \times \frac{-3}{14} \\= \frac{-46}{14}\\ = -3.28[/tex]

Note that from the calculation the quotient of a positive number to a negative number returns a negative number. Based on Ankur's answer, he got a postive value which is one of his errors. He found out that the quotient of a positive number and a negative number is positive which is wrong.

Hence the correct option is C

Answer:

Step-by-stepAnkur found that the quotient of a positive number and a negative number is negative

Step-by-step explanation:

Given that:

Quotient of 15 and one-third divided by (negative 4 and two-thirds) = 3

Mathematically,

( 15 1/3) ÷ (-4 2/3) = 3

Here,

Dividend = 15 1/3 (positive)

Divisor = - 4 2/3 (negative)

Dividing a positive Dividend by a negative Divisor will always give a negative quotient

Hence,

15 1/3 = 46 / 3

-4 2/3 = - 14 / 3

46/3 ÷ - 14/3

= 46/3 * -3 / 14

Ankur must have either forgotten or neglected the negative sign in the divisor explanation:

so the answer is b

Using an exponential function, it is found that he must spend $118,214 in 11 years to keep the same standard of living.

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which:

His current cost of living is of $50,700, which increases by 8% yearly, hence A(0) = 50700, r = 0.08, and the equation is:

[tex]A(t) = A(0)(1 + r)^t[/tex]

[tex]A(t) = 50700(1 + 0.08)^t[/tex]

[tex]A(t) = 50700(1.08)^t[/tex]

After 11 years, the cost will be given by:

[tex]A(11) = 50700(1.08)^{11} = 118214[/tex]

Answer:

x = 6

Step-by-step explanation:

Ok first you need to get to combine like terms, so first subtract six from the left so it cancels out the left side and what you do to one side you have to do it to the other so after you do that you get

-3x = 2x -30

then you subtract 2x from the right side and 2x on the left side getting

-5x = -30

your  goal is to get  by itself so what you can do is divide -5 on both sides getting

x = 6

if you are wondering why its a positive and not a negative its because a negative divided or multiply by a negative makes a positive.

Answer:

x=6

Step-by-step explanation:

-3x+6=2x-24

6=5x-24

30=5x divide both sides by 5

x=6

24: 2 x 2 x2 x 3

gcf/hcf : 2

4 and 6 :

6: 2x 3

gcf/hcf : 2

why 6 and 12 don't work

6: 2 x 3

12: 2 x 2 x 3

they have 3 in common as well, meaning the hcf/gcf would be 2 x 3 which is 6, not 2

Answer:

y-5=-2/3(x-(-7))

Step-by-step explanation:

I just learned this recently as well so bare with me.

So the point slope form is y-y1=m(x-x1)

So first we have to find the slope. So we do 5-(-1)/-7-1=-6/8=-3/4

So now, we just have to plug in the numbers.

So y-5=-2/3(x-(-7)).

I know that looks a little funky but if you used the slope intercept form, you would get the same answer if you just simplified this version. Of course, you don't have to simplify this version because this version is completely acceptable.

I hope this helped.
