Solve:
-4 + x = 6
A)-24
B)-10
C)-2
D)10

Answers

Answer 1

Answer:

x = 10 so D

Step-by-step explanation:

-4 + x = 6

add 4 both sides to get the x by itself

so 4 + 6 = 10

then the final answer is  x = 10

Answer 2

Answer:

You have a negative 4 being added to the variable. To solve you need to use the opposite operation (what is the opposite of addition?)

For example:

7 = -3 + h

Subtraction -3 from each side.

7 -(-3) = -3- (-3) + h

10 = h

A 5 foot tall pole casts a 3 1/3 foot shadow. At the same time an oak tree casts a 20 foot shadow. How tall is the tree?

Answers

Answer:

30 feet tall

Step-by-step explanation:

Set up a proportion where x is the height of the tree

[tex]\frac{5}{3\frac{1}{3} }[/tex] = [tex]\frac{x}{20}[/tex]

Cross multiply and solve for x:

100 = 3[tex]\frac{1}{3}[/tex]x

30 = x

So, the tree is 30 feet tall

y = - 2

Answer for 7: C

Answer for 9: A

Step-by-step explanation for 7:

Because the variable is an exponent, we know there are no real numbers which cannot be placed in the exponent. Therefore, the domain is all real numbers.

Step-by-step explanation for 9:

Test a few values for x. Notice as the x value gets higher, the y value gets exponentially higher. Notice as the x value gets lower, the y value approaches 0, but no value of x will have y equal to or less than 0. Therefor, the asymptote, or line that cannot be crossed is 0 - making A the correct solution.

in the diagram the measure of angle one is 3X the measure of angle two is 12 X what is the measure of angle 4

Answers

Answer:

144°

Step-by-step explanation:

m<1 =3x

m< 2= 12x

1&2 are supplementary angles, so

3x+12x= 180

15x=180

x= 12°

measure of angle 4 equals the measure of angle 2

because they're head opposite angles

m<4= 144°

(25-a) divided by 7=3

Answers

Answer:

a = -0.57

rounded to the nearest tenth: a = -0.6

Step-by-step explanation:

(25 - a) ÷ 7 = 3

25 - a ÷ 7 = 3

25 ÷ 7 - a = 3

3.6 - a = 3

3.57 - 3.57 - a = 3 - 3.57

a = -0.57

The value of "a" in the equation (25 - a) ÷ 7 = 3 is 4.

To find the value of "a" in the equation (25 - a) ÷ 7 = 3.

we can solve for "a" by isolating it on one side of the equation.

(25 - a)/7 = 3.

Multiply both sides of the equation by 7 to get rid of the division:

7(25 - a)/7 = 3 × 7.

25 - a = 21.

To isolate "a," subtract 25 from both sides of the equation:

25 - a - 25 = 21 - 25.

Simplifying further, we get:

-a = -4.

Multiply both sides of the equation by -1 to solve for "a":

-1 × (-a) = -1× (-4).

a = 4.

Therefore, the value of "a" in the equation (25 - a) ÷ 7 = 3 is 4.

y +4 = 1/2 (x + 3) distributive property

y + 4 = 1/2x + 1.5

y= 1/2x - 5/2 subtraction (you subtract 4 from both sides) (-5/2 = -2.5)

therefore your equation is y = 1/2x - 5/2

(4) Why then do most schools still implement the antiquated policy of summer vacation? (5) As students and teachers, don't we also make up the "real world"?
