Answer:
66
Step-by-step explanation:
6 × 9 + 4 × 3
We use PEMDAS to determine the order in which the mathematical operations would be carried out.
PEMDAS is an acronym for Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.
Multiplication comes first so;
6 × 9 + 4 × 3
54 + 12
We can then add both numbers.
54 + 12 = 66
Which equation can be used to find the value for X?
Answer:
(3x-5) + 2x = 90
Step-by-step explanation:
We know that there are 180 degrees in a triangle. We also know that one angle is 90 degrees.
This means that (3x-5) + 2x = 90.
What is the number model
Answer:
A number model in math is a sentence that illustrates how the parts of a number story are related. The equation may include addition, subtraction, division and multiplication and may be expressed as words or in number form.
Step-by-step explanation:
Answer:
Sometimes abbreviated as model or model no., a model number is a unique number given to each product made by computer hardware manufacturers. Model numbers allow manufacturers to keep track of each hardware device and identify or replace the proper part when needed.

What is the solution to this system of equations? 5x + 2y= 29
x + 4y = 13
A x = 5, y = 3
B. x=2, y=5
C. X= 5, y = 2
D. x= 3, y = 2
Answer:
C
Step-by-step explanation:
Given the 2 equations
5x + 2y = 29 → (1)
x + 4y = 13 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the y- term
- 10x - 4y = - 58 → (3)
Add (2) and (3) term by term to eliminate y
- 9x + 0 = - 45
- 9x = - 45 ( divide both sides by - 9 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (2)
5 + 4y = 13 ( subtract 5 from both sides )
4y = 8 ( divide both sides by 4 )
y = 2
Solution is x = 5, y = 2 → C
Answer:
c) x = 5, y = 2

Jill orders t-shirts on Amazon. Each shirt costs $15.00 including tax. A one-time shipping fee of $3.25 is added to the cost of the order. The total cost of Jill's order is $78.25. How many t-shirts did Jill order? *
Answer:
5 shirts
Step-by-step explanation:
Step one:
given data
Each shirt costs $15.00 including tax.
A one-time shipping fee of $3.25
The total cost of Jill's order is $78.25
Step two:
let the number of shirts be x
so
y=15x+3.25
for y= $78.25, let us find x
78.25=15x+3..25
collect like terms
75= 15x
divide both sides by 15
x=75/15
x=5
Aliza needs to run at a rate faster than 8.8 feet per second in order to exceed her fastest time in a race. After running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. He converts the average rate to feet per second as shown below: He concludes that she is not running fast enough to exceed her fastest time. What errors did the coach make? Check all that apply. He used an incorrect time ratio converting hours to minutes. His units do not cancel. He used an incorrect distance ratio converting miles to feet. He incorrectly concluded that she is not running fast enough. He cannot determine her average rate in miles per hour after only 15 minutes.
Answer:
a. He used an incorrect time ratio converting hours to minutes.
d. He incorrectly concluded that she is not running fast enough.
Step-by-step explanation:
Looking at the Coach's method of conversion when converting time, he assumed that an hour had 15 minutes instead of 60 minutes. He therefore did not use the correct time ratio to convert hours to minutes.
The coach's calculations yielded an answer of 34 ft/s. This is way faster than 8.8 ft/ s so his deduction that she was not running fast enough to beat her fastest time is incorrect because at that inhumane speed, she did.
Answer: A.)He used an incorrect time ratio converting hours to minutes.
D.)He incorrectly concluded that she is not running fast enough.

In triangle QRS the measurement of an angle RSQ is 29.1 and the measure of angle QRS is 70 degrees what is the measurement of sqr
Answer: The measure of ∠SQR= 80.9°
Step-by-step explanation:
Given: In triangle QRS,
∠ RSQ = 29.1° and ∠QRS=70°
To find: ∠SQR
Angles sum property of triangle = Sum of all the angles in a triangle is 180°.
For Δ QRS,
∠SQR + ∠ RSQ +∠QRS = 180°
⇒ ∠SQR + 29.1° + 70° = 180°
⇒ ∠SQR + 99.1° = 180°
⇒ ∠SQR= 180°-99.1
⇒ ∠SQR= 80.9°
Hence, the measure of ∠SQR= 80.9°

Find the area of the triangle with A = 60°, b = 11 feet, and c = 8 feet. Round to the nearest tenth.
Answer:
41.25 ft^2
Step-by-step explanation:
Literally all you need to do is Pythagorean Theroem.
a = ?
b = 11ft
c = 8ft
a^2 + b^2 = c^2
a^2 + 11^2 = 8^2
a^2 + 121 = 64
64 - 121 = a^2
a = 7.5
Then area of a triangle formula is (bh)/2
(11 x 7.5)/2 = 41.25

Answer:
-2 tiles
Step-by-step explanation:
In each figure, 5 tiles are added.
Subtract 5 from how many tiles are in Figure 2 (8 tiles) & you get 3.
3 is how many tiles are in Figure 1, meaning you need to subtract 5 again to see how many are in Figure 0! 3-5 = -2.

Answer:
We conclude that:
m∠XWY = 41°Step-by-step explanation:
Given
m∠VWX = 139°
m∠YWZ = 23°
To determine
m∠XWY = ?
We know the measure of the angle of a straight is 180°.
As m∠VWX and m∠XWY lie on a straight line.
Thus, the sum of m∠VWX and m∠XWY must be 180°
so we get the equation
m∠VWX + m∠XWY = 180°
Given that m∠VWX = 139°
so substituting m∠VWX = 139° in the equation m∠VWX + m∠XWY = 180°
139° + m∠XWY = 180°
m∠XWY = 180° - 139°
m∠XWY = 41°
Therefore, we conclude that:
m∠XWY = 41°There are 32 students on a large bus, and the rest are on a smaller bus. If 30% of the students are on the smaller bus, how many total students are on the two buses?
