Answer 1

Answer:

z = 13 degrees

Step-by-step explanation:

1.) Those two angles add up to 90 degrees, so we can say that 5z - 6 + 2z + 5 = 90

2.) Simplify both sides to get 7z - 1 = 90.

3.) Isolate Variable by adding 1 on both sides to get 7z = 91.

4.) Divide by 7 on both sides to find that z = 13 degrees.

Answer 2

Answer:

z = 13

Step-by-step explanation:

5z - 6 + 2z + 5 = 90

7z - 1 = 90

7z = 91

z = 13

On Monday, Samuel sells 16.9lb of cans, and gets 16.9×$0.50=$8.45. On Tuesday, he sells 12.6lb of cans, and gets 12.6×$0.50=$6.30 In total, he receives $8.45+$6.30=$14.75. Since each battery costs $5.50, he can buy $14.75÷$5.50≈2.68. Since he can't buy fractions of a battery, he can buy 2 batteries.

Don't overthink it darling, just plug in the numbers to the equation. When you do that, you get 3+(5 + 4)(8 - 6). You add the 5 and 4 and subtract the 8 and 6. Your equation now is 3+9*2. Being there is no sign between the two )( it means your multiplying. So you do 9*2 and you get 18+3 and you get your answer of 21.

Solve for x.

First angle is 56 degrees, second is x-14.

Answers

Since the total angle is a right angle, we know it is 90 degrees. Then

56 + (x-14) = 90

And then we can subtract 56 on both sides to simplify this to

x - 14 = 34

Adding 14 on both sides we get

x = 48

x should be 48!!!!!!!!!

Similar triangles means all angles of one triangle are same as the other triangle . Triangle BAC and DAE are equal by construction as they lie within the same rays. Triangle BCA and DEA are right angles. Sum of all angles of triangle is 180 degree. Since two of the angles are same say X and 90, the third has to be the same such that ABC and ADE are both 180- X -90 Ie 90-X.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Solutions of an equation mean the value of the variable that would make the given equation true.

The solution to the equation -16.2 = x - (- 9 x 3) is 43.2.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 5 is an equation.

3x + 5x + 4 = 9 is an equation.

We have,

-16.2 = x - (-9 x 3)

Solutions of an equation mean the value of the variable that would make the given equation true.

Remove the parenthesis.

-16.2 = x + 27

Subtract 27 on both sides.

-16.2 - 27 = x + 27 - 27

-16.2 - 27 = x

x = -43.2

We can cross-check.

-16.2 = x - (- 9 x 3)

-16.2 = 43.2 - (-27)

-16.2 = -43.2 + 27

-16.2 = -16.2

Thus,

The solution to the equation -16.2 = x - (- 9 x 3) is 43.2.

Write in slope-intercept form an equation of the line that passes through the given points.

(2, 4), (3, 6)

(Please write process so i can learn ty)

Answers

Answer:

y = 2x

Step-by-step explanation:

Let's first find the slope:

m = (y₂ - y₁)/(x₂ - x₁)

m = (6 - 4)/(3 - 2) = 2/1 = 2

Now let's use point-slope form:

y - y₁ = m(x - x₁)

(For x₁ and y₁, you can use either (2,4) or (3,6), but I'm gonna use (2,4))

y - 4 = 2(x - 2)

y - 4 = 2x - 4

y = 2x

That's your answer.

210/7 = 30 so there are 30 M&Ms per ounce. 30 * 3 = 90 so there are 90 M&Ms in 3 ounces. Each M&M weighs 1/30 of an ounce and in decimal form that is 0.0333 repeating so rounded to the nearest hundredth it would be 0.03 ounces per M&M.

Which system of equations has a solution of (–3, –1)? NO LINKS OR SAYINGS
A: y = –3x – 10
y = x + 4

B: y = –3x – 1
y = –x – 3

C:y = 2x – 1
y = 5x + 2

D:
y = 2x + 5
y = 5x + 14

Answers

The answer is b my friend

The answer is D. First you distribute 5 to the top equation so the two x variables can cancel out.
5(y=2x+5) the result would be 5y=10x+25

Then take the other equation and distribute -2 into it since a negative and positive cancel out. It would look like this:
-2(y=5x+14) the final product would be -2y=-10x-28
With this you can now add the two equations. So,,
+5y=10x+25
-2y=-10x-28
You add the like terms and end up with 3y=-3. Divide the 3 from 3y to the other side This gives you the y value(-1).You can now look for the x value by replacing the y from one of the two equations. You add like terms and end up with a x value of -3.
In conclusion the answer to your question is D. Y=2x+5. Y=5x+14

Nadia charges $6.50 an hour for babysitting. She babysits 19.50 hours the first week of the month and 19 hours the second week of the month.

Suppose Nadia raises her rate by $0.65 an hour. How many hours would she need to work to earn the same amount of money she made in the first two weeks of the month?

Complete the explanation and give your answer.

Nadia's new hourly rate is $___ .She would need to work ___ hours in the next two weeks to make the same amount she made in the first two weeks.

Answers

Answer:

Her new hourly rate is $7.15. She would need to work 35 hours in the next two weeks to make the same amount she made in the first two weeks

Step-by-step explanation:

6.50+.65=7.15 which is the new hourly rate

19+19.50 to find how many hours in total which is 38.5 hours

you multiply the rate of 6.50 by 38.5 and you get $250.25 in 2 weeks for the old rate.

I just multiplied until I found the amount of hours to make 250.25 with the new rate.

7.15x35=250.25

Her new rate is 7.15$ per hour. She would need to work 35 hours to make the same amount of money in the next two weeks.

The is because if you add 19.50+19 you get 38.5 hours and she would have made 250.50$

Now if you add 6.50+0.65 that is 7.15 if you divide 250.50 by 7.15 you will get 35.
