Step-by-step explanation:
In isoceles triangle two sides are equal and two angles are equal.
Then,
∠R = ∠T = (5x-40)°
Then,
∠RTS + ∠STU = 180° (bcoz it lies on a straight line)
(5x-40) ° + 5x = 180°
10x = 220°
x = 22°
Therefore,
Option A is correct✔

What is the solutions of the following system of equations.
y = -2x + 2
y = x - 1
Answers
Answer:
x = 1, y = 0
Step-by-step explanation:
Given the 2 equations
y = - 2x + 2 → (1)
y = x - 1 → (2)
Substitute y = x - 1 into (1)
x - 1 = - 2x + 2 ( add 2x to both sides )
3x - 1 = 2 ( add 1 to both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting into (2)
y = 1 - 1 = 0
Solution is (1, 0 )
Which of the following system of inequalities is the graph below?
HELP ME PLEASE !!!
Answers
Answer:
2nd answer choice
Step-by-step explanation:
First, you see which inequalities are represented in the graph. When doing this, I just temporarily the signs to equal signs so just basically ignore the inequalities. Then, when you find the ones with the right numbers, you can worry about the inequalities. Remember that greater than is always the side where the y values increase and less than is always where the numbers on the y axis decrease. Also, pay attention to the equal than sign. If it has a line under the sign, the line has to be solid while if there is no line, then it is dashed. In this problem, The first equation represents the dashed line and the second is the solid line.

You start a new job. After w weeks, you have (10w+110) dollars in your savings account and (36w+25) dollars in your checking account.
Answers
Answer:
(46w+135) dollars
Step-by-step explanation:
Given that,
Amount in savings account = (10w+110) dollars
Amount in checking amount = (36w+25) dollars
We need to find an expression that represents the total in both accounts. It is simply the sum of amount in the savings account and checking amount.
Sum = (10w+110) dollars + (36w+25) dollars
= (10w+36w) + (110+25)
= (46w+135) dollars
Hence, the required expression is (46w+135) dollars

32. Exercise Ahmit gets
exercise on the weekend by
working around the house.
On Saturday, he worked for
3 hours mowing the lawn and
raking leaves; He burned
885 Calories.
a. Write a system of
equations that can be used
to describe the amount
of time Ahmit worked and
the number of Calories
he burned by mowing
and raking
b. Determine how much time Ahmit spent on mowing and raking.
Answers
Answer:
X: time mowing lawn (325 Cal/hour)
Y:time raking leaves (275 Cal/hour)
325X + 275Y = 885
3 - X = Y
(1.2 hours mowing the lawn, 1.8 hours raking leaves)
Step-by-step explanation:
you forgot to include vital information. When ahmit rakes leaves, he loses 275 calories per hour. When he mows the lawn, he loses 325 calories per hour according to the textbook you got this from. If he works for 3 hours, you need to find the portion of each activity he did by working backwards from the total calories lost, 885.

Step 2: Solve for x
Combine like terms: 6x + 3 = 6x + 3Subtract 3 on both sides: 6x = 6xDivide 6 on both sides: x = xHere we see that x does indeed equal to x.
∴ x = infinite amount of solutions.
2x + 3 + 4x = 6x + 3
Combine the like terms on the left side
2x + 4x = 6x
6x + 3= 6x + 3
Subtract 3 from each side
6x = 6x
Divide each side by 6
x = x

Area of triangle:

= 275.5 in^2
Area of rectangle:
A= l * w
= (29) * (10)
= 290 in^2
Total Area:
275.5 + 290 = 565.5 in^2
Hope this helps! Have a great day :)
Answer:
565.5 in
Step-by-step explanation:
The area for a rectangle is A = lw
So A = (29)(10)
A = 290
The area for a triangle is A = 1/2bh
So A = 1/2(29)(19)
A = 1/2(551)
A = 275.5
You combine the two numbers to get a total area of 565.5 in

Find the measure of the angle indicated
Answers
Answer:
60° and 67°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(49)
17x + 8 is an exterior angle of the triangle, thus
17x + 8 = 50 + 10x ( subtract 10x from both sides )
7x + 8 = 50 ( subtract 8 from both sides )
7x = 42 ( divide both sides by 7 )
x = 6
Thus
∠ C = 10x = 10(6) = 60°
(50)
99° is an exterior angle of the triangle, thus
2x + 10 + 6x + 1 = 99 , that is
8x + 11 = 99 ( subtract 11 from both sides )
8x = 88 ( divide both sides by 8 )
x = 11
Thus
∠ T = 6x + 1 = 6(11) + 1 = 66 + 1 = 67°

Both the domain and range are the set of all real numbers. For the absolute value function f(x)=|x| f ( x ) = | x | , there is no restriction on x . ... For the cubic function f(x)=x3 f ( x ) = x 3 , the domain is all real numbers because the horizontal extent of the graph is the whole real number line. this is the best i can do if its not helpful i guess u can ask ur teacher.
