Answer:
x= 3
y= 31
Step-by-step explanation:
4y + 21 = 145
subtract 21 from both sides
4y = 124
divide both sides by 4
y = 31
3x + 26 = 35
subtract 26 from both sides
3x = 9
divide both sides by 3
x = 3
hope this helps :)
6x^2=294 find x pls give steps
Answer:
Step-by-step explanation:
Step 1: Divide both sides by 6.
[tex]\frac{6x^2}{6}[/tex] = [tex]\frac{294}{6}[/tex]
[tex]x^{2}[/tex] = 49
Step 2: Take the square root.
x = [tex]\sqrt{49}[/tex]
x=7 (because 7×7=49
If a right triangle has side lengths of 3 feet and 4 feet, what is the length of the hypotenuse?
Answer:

The painting shown at the right has an area of 460in^2. What is the values of x?
Answer:
45x8 i think
Step-by-step explanation:
-x = 10
I will____ both sides by_____
x= _____
Answer:
I will subtract both sides by 10. X=-10
Step-by-step explanation:
X= -10 because if you subtract it to -x it will cancel out the negative.
Answer:
I will divide both sides by -1.
x = -10
Step-by-step explanation:
To solve this, we have to isolate x on one side of the equation. In this equation, 10 = -x.
Remember that the coefficient of a single variable is always 1, so 1x = x. We have -x, which means it's actually -1x. Solve using -1x instead of -x.
[tex]-x=10[/tex]
[tex]-1x=10[/tex]
Divide both sides by -1 to isolate x.
[tex]\frac{-1x}{-1} =\frac{10}{-1}[/tex]
Simplify.
[tex]x = -10[/tex]
x is equal to -10.
The answer is I will divide both sides by -1.
x = -10

A student from the community college is selected at random. Find the probability that the student is at last 31. Round approximations to three decimals places
Answer:
0.077
Step-by-step explanation:
From the table :
Number of students aged 31 - 35 = 60
Number of students over 35 = 26
Total number of students = total possible outcomes = 1123
Required outcome = (students aged 31 - 35) + over 35 = 60 + 26 = 86
Probability = required outcome / Total possible outcomes
Probability (at least 31) = 86 / 1123 = 0.0765
= 0.077 (3 decimal places)

Find the measure of x.
Answer:
C
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent
x is the angle between line with 3 strokes and 2 strokes
The corresponding angle is therefore ∠ C
∠ C = 180° - (63 + 29)° = 180° - 92° = 88°
Then x = 88 → C
Find the volume of a pyramid with a square base that has a side measuring 10 cm and a height of 15 cm
Answer:
Volume = 500 cm³
Step-by-step explanation:
Given the following data;
Side length of the base = 10cm
Height = 15 cm
To find the volume of pyramid with a square base;
Mathematically, the volume of a pyramid with a square base is given by the formula;
Volume of square-based pyramid = A(h/3)
Where;
A is the area of the square base.
h is the height of the pyramid.
First of all, we would find the area of the square base;
Area of square, A = L²
A = 10²
A = 100 ft²
Next, we find the volume of the square-based pyramid;
Volume = 100(15/3)
Volume = 100 * 5
Volume = 500 cm³
James is shopping for hiking boots for a trip he will take in 3-months. He has $150 saved and is saving $20/week. The boots he wants are normally $240, but are on sale this weekend for 20% off. Should James....
Answer:
Use his savings to buy the shoes now and put the amount he is short on a credit card.
Step-by-step explanation:
Due to the discount on sale, then it is advisable James buys with his savings and put the balance amount on his credit card. By virtue if the discount, James will be able to save ;
(0.2* $240) = $48. This discount will be a good bargain and will be unavailable by the time his savings can buy in full. However, since James has a repayment channel (his $20/week) saving, then he can put the amount left to balance in his credit card and sort his credit balance later.

Answer:
A. [tex]Log_p N = b \ and \ b^p = N[/tex]
Step-by-step explanation:
A. The given options are;
[tex]Log_p N = b \ and \ b^p = N[/tex]
For [tex]Log_p N = b[/tex] we have;
[tex]p^b = N[/tex]
However;
[tex]b^p = N[/tex]
Where, p ≠ b
[tex]p^b \neq b^p[/tex]
Therefore;
N ≠ N for the given pair and the pair are therefore, not equivalent
B. x = √y and [tex]x = y^{1/2}[/tex]
We note that
x = √y = [tex]y^{1/2}[/tex]
We have;
x = [tex]y^{1/2}[/tex], by transitive property
Therefore, the pair, x = √y and [tex]x = y^{1/2}[/tex] are equivalent
C. [tex]Log_b N = p \ and \ b^p = N[/tex]
From [tex]Log_b N = p[/tex], we have;
[tex]b^p = N[/tex]
Therefore, [tex]Log_b N = p \ and \ b^p = N[/tex] are equivalent pairs as [tex]b^p = N[/tex] can be obtained from [tex]Log_b N = p[/tex]
D. ㏑x = y and x = [tex]e^y[/tex]
[tex]ln \ x = ln_e \ x = y[/tex], therefore, by rules of logarithm, we have;
x = [tex]e^y[/tex]
Therefore, ㏑x = y and x = [tex]e^y[/tex] are equivalent pairs, as x = [tex]e^y[/tex] can be obtained from ln x.
Therefore;
The option which are not equivalent pair is option is [tex]Log_p N = b \ and \ b^p = N[/tex]
Evaluate the expression.

WHich one is equal to 932.076 (A) Nine hundred thirty two and 76 thousandth (B) 9·100+32+ 76 100 (C) 93·10+2+ 7 10 + 6 100 (D) 9·100+3·10+2+ 76 1000 (E) 93·10+2·1+ 7 100 + 6 1000 (F) Nine hundred thirty two and 76 hundredth
The correct place value for the expression 932.076 is defined by option A, D, and E.
Expression is equal to 932.076,
The explanation of the place value of all the options are as follow,
Nine hundred thirty-two and 76 thousandth = 932.076
Option (A) is correct answer.
9·100 + 32 + 76/100
= 900 + 32 + 0.76
= 932.76
Option (B) is not the correct answer.
93·10 + 2 + 7/10 + 6/100
= 930 + 2 + 0.7 + 0.06
= 932.76
Option (C) is not the correct answer.
9·100 + 3·10 + 2 + 76/1000
= 900 + 30 + 2 + 0.076
= 932.076
Option (D) is the correct answer.
93·10 + 2·1 + 7/100 + 6/1000
= 930 + 2 + 0.07 + 0.006
= 932.076
Option (E) is the correct answer.
Nine hundred thirty-two and 76 hundredth = 932.76 not 932.076
Option (F) is not the correct answer.
Therefore, the correct place value of the given expression is equal to option A, D, and E.

Salma and jared each threw 5 darts at the target shown. Salma scored 19 points by landing 2 darts in A and 3 in B.How many points are given for a dart landing in A?
Answer:
5
Step-by-step explanation:
Salma and Jared each threw 5 darts at the target shown. Salma scored 19 points by landing 2 darts in A and 3 in B. Jared scored 17 points by landing 1 dart in A and 4 in B. How many points are given for a dart landing in A?
this can be solved using simultaneous equation. Two equations can be formed from the question
2a + 3b = 19 equation 1
1a + 4b = 17 equation 2
Multiply equation 2 by 2
2a + 8b = 34 equation 3
Subtract equation 1 from 3
5b = 15
divide both sides of the equation by 5
b = 3
Substitute for b in equation 1
2a + 3(3) = 19
2a = 9 = 19
collect like terms
2a = 10
divide both sides of the equation by 2
a = 5
