Answer:
23
Step-by-step explanation:
90 + 67 + x = 180
157 + x = 180
x = 23
180=x+67+90 (combined like terms)
180=x+157 (subtract 157 from both sides)
23=x

Answer:
11/15
Step-by-step explanation:
Answer:
- 11 / 15
Step-by-step explanation:
x = - 2
y = - 1 / 5
1 / 3 + x . z
= 1 / 3 + ( - 2 ) . ( - 1 / 5 )
= 1 / 3 + ( - 2 . - 1 ) / 5
= 1 / 3 + 2 / 5
1 / 3
= ( 1 / 3 ) x ( 5 / 5 )
= ( 1 x 5 ) / ( 3 x 5 )
= 5 / 15
2 / 5
= ( 2 / 5 ) x ( 3 / 3 )
= ( 2 x 3 ) / ( 5 x 3 )
= 6 / 15
1 / 3 + 2 / 5
= 5 / 15 + 6 / 15
= ( 5 + 6 ) / 15
= 11 / 15
Claire's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This relationship can be represented by the equation y represented by the equation y = 56 + 7.1x, where y represents the expected quiz score and x represents hours spent on homework that week. What is the meaning of the x-value when y = 92?
the change in expected quiz for every additional one hour students spend on their homework.
a student's expected quiz score if they spent 1 hours on their homework.
the number of hours a student should spend on their homework to expect a score of 92 on the quiz.
a student's expected quiz if they spent 92 hours on their homework.
Answers
Answer: t = 5.7 hours
Step-by-step explanation:
y=56+7.1x where x is the time spent studying. If y=92, this equation would preduct that the student spent t hours studying. Find t:
92=56+7.1x
36=7.1t
t = 5.07 hours to achieve the 92 score.

Plug the value of x and y :[tex] \longrightarrow \: \large{ \tt{ - 2 \times ( - 2) + 3 \times ( - 5)}}[/tex]
When negative integer is multiplied by negative integers , we get positive integer & when positive integer is multiplied by negative integer , we get negative integer.[tex] \longrightarrow \large{ \tt4 + ( - 15){}}[/tex]

Answers
Explanation: so for this equation we are determining which coordinates are in the graph, now it wants us to be looking at q—>N so we can immediately rule out A and B since they would be on the line past Q in the wrong way, now we look at the second pair of numbers since the first ones are the same for C and D, we see that Cs is at 3, -8 and since this is both past Q to the right and it doesn’t lie on the line we can conclude that the answer is D. We can the check this by looking at the 2 points on the line.

Describe what is meant by the slope of a non-vertical line. Explain how your description relates to the definition of slope.
Answers
Answer: A verticle line does not have a slope.
Step-by-step explanation: Slope is the rate of change of y for each change in x. y = 2x is a line with slope of 2. Each time x is incremented by 1, y will increase by twice (2x) that amount. There is no slope to a verticle line, unless you want to call it infinite. The value of y is not defined by x.

find the value of each variable 2x+4x+108
Answers
Answer:
Step-by-step explanation:
2x + 4x + 180
We have to do combine like terms.
2x and 4x are like terms, so add 2x to 4x. Which gives you 6x. Now you have the expres 6x + 180. You can’t find the variable for this expression, its unsolvable. If you meant, “2x + 4x = 180” Then yes, it would be solvable.
All you would have to do Is, 2x + 4x which gives you 6x, and now divide both side by 6. 6x divided by 6, the two 6 would cancel out, and 180 divide by 6, leaving you with 30. So x should equal to 30.

1) 80 units because when you sub h = 9, you get 400 as the answer and because it’s a square, you square root 400 which is 20 units per side.
2) x = 7cm because when you multiply (x + 5)(x - 3), you get x^2 + 2x - 15 = 48 and when you solve it you get x is equal to 7, -9, because the length of the rectangle is positive x is equal to 7.
3) the binomial would be (9x + 1)^2.

Step-by-step explanation:
It's hard to see your photo but if that say m∠T than your answer would be
m∠ L.
The drawings are saying the the triangles are congruent which means all the interior angles of one triangle are congruent to the angles of the second triangle. m∠M = m∠J, m∠K = m∠E and m∠L = m∠T
Since you have two of the angles, you can also determine what m∠L and m∠T is equal to. The sum on all interior angles must be 180 degrees.
