HELP!!
Are triangles RST and RDC congruent?

A. Yes by AA

B. Yes by SSS

C. Yes by SAS

D. They are not similar

Answer:

4

Step-by-step explanation:

Lets make [tex]x[/tex] be the ? in the equation.

That becomes ([tex]x[/tex] x 3) - 3 = 15.

First you have to add 3 on both sides. After doing that it gets to ([tex]x[/tex] x 3) = 15 - 3.

Then you simplify it to 3[tex]x[/tex] = 12.

Now you divide 3 on both sides. That gets to [tex]x[/tex] = 4 after doing it.

Answer:

72

Step-by-step explanation:

-2 x -4 = 8

8 x 9 = 72

Hope this helps! Please mark Brainliest!

Answer:

72 = Positive

Step-by-step explanation:

The property we use,

→ Associative property

Now the product will be,

→ (-2 × -4) × 9

→ 8 × 9 = 72

→ -2 × (-4 × 9)

→ -2 × (-36) = 72

Then the required sign is,

→ Positive (+ve)

Hence, the product is 72.

Answer:

Answer:

A) true

B) false

c) true

d) true

Step-by-step explanation:

A) angles 7 and 6 are vertical angles, which means they're equal.

so, A is True.

B) angles 7 and 5 are supplementary angles, which means they add up to 180. 135 + 55 is 190. so B is False

C) angle 7 is equal to angle 3, which is supplementary to angle 1.

so, 55 + angle 1 = 180

55 + angle1 = 180

subtract 55 from both sides of the equation

angle1 = 180 - 55

angle 1 = 125.

angles a and 4 are vertical angles, so they are equal. if you add them together that would be 125 + 125

125 + 125 = 250

so, C is True

D) angles 1 and 6 are supplementary, and angles 2 and 7. since they both add together to make 180, D is True

Answer:

190 miles

Step-by-step explanation:

Answer:

Step-by-step explanation:

The pair of number that makes the expression [tex]a^x = ax[/tex] true are 2 and 2 as shown:

where a = 2 and x =2

2² = 2*2

2² = 4

and:

2*2 = 4

Hence 2²  = 2(2) = 4 making the expression [tex]a^x = ax[/tex] true for both pair of numbers

Also the number pair 1 and 2 makes the expression correct as shown:

[tex]2^1 = 2(1)\\2 = 2 (true)[/tex]

Answer:

x=m-z

Step-by-step explanation:

The first step is to isolate x and to do this we got to subtract m from both sides which would give us -m+z=-x, the next step is to get x to be positive so we have to divide both sides by negative 1 which is because there is a 1 beside all of the values, and when we do divide both sides by negative 1 we get x=m-z

Step-by-step explanation:

Given that:

Jacinda = 16 baskets

Greta = 4 baskets

The number of baskets Jacinda made is how many times more than the number of baskets Greta made?

To obtain this :

Number of baskets Jacinda made / Number of baskets Greta made

If Jacinda's basket = J ; Greta's basket = G

J / G

16 / 4 = 4

Hence, Number of basket Jacinda made is 4 times more than that made by Greta

Answer: Is it not 6km an hour?

Answer:

He made $581 if he worked 44 1/2 hours last week

Step-by-step explanation:

Let us solve the question

∵ Henry makes $12.50 per hour for the first 40 hours

∵ For each additional hour, he makes $18 per hour

→ We need to find how much he made if he worked 44 1/2 hours

→ At first, find his earning for the first 40 hours

∵ His earning in the first 40 hours = 40 × 12.50

∴  His earning in the first 40 hours = $500

→ Find how many hours he worked after the first 40 hours

∵ 44 1/2 - 40 = 4 1/2 hours

∴ He worked 4 1/2 hours over the first 40 hours

→ Find his earning from them

∵ His earning in 4 1/2 hours = 4 1/2 × 18

∴ His earning in 4 1/2 hours = $81

→ Now add the two amounts to find his total earning

∵ His total earning = 500 + 81

∴ His total earning = $581

∴ He made $581 if he worked 44 1/2 hours last week

Answer:

5x-11

Step-by-step explanation:

This is the word problem as an expression

5x-55 represents the mathematical expression for the given statement.

Expressions in maths are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is a statement, the product of five and a number, decreased by eleven,

Let the number be x, converting the given statement, into a mathematical expression, we get

5(x-11)

= 5x-55

Hence, 5x-55 represents the mathematical expression for the given statement.

Step-by-step explanation:

Just keep adding my friend

Answer:

angle 2 = 37⁰

angle 3 = 153⁰

angle 4 = 37⁰

Step-by-step explanation:

I guess this refers to two intersecting lines which form 4 angles.

Angles 1 and 2 are supplementary angles whose sum is 180⁰.

Angle 1 + angle 2 = 180⁰

143⁰ + angle 2 = 180⁰

angle 2 = 180⁰ - 143⁰

angle 2 = 37⁰

Angles 1 and 3 are vertical angles so do with angles 2 and 4. Therefore it is easy to find their measures because vertical angles are congruent in measures.

Answer:

(3x−y)(x+7y)

Step-by-step explanation:

Factor (2x+3y)^2−(x−4y)^2

3x^2+20xy−7y^2

=(3x−y)(x+7y)

Answer:

(3x - y)(x + 7y)

Step-by-step explanation:

Given

(2x + 3y)² - (x - 4y)² ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Here a = 2x + 3y and b = x - 4y , then

(2x + 3y + x - 4y)(2x + 3y - (x - 4y))

= (3x - y)(2x + 3y - x + 4y) = (3x - y)(x + 7y)

Thus

(2x + 3y)² - (x - 4y)² = (3x - y)(x + 7y) ← in factored form
