Benny spent half of his allowance going to the movies. He washed the family
car and earned 8 dollars. What is his weekly allowance if he ended with
13 dollars ?
Let it be x
He spent x/2 dollars then
[tex]\\ \sf\longmapsto \dfrac{x}{2}+8=13[/tex]
[tex]\\ \sf\longmapsto \dfrac{x+16}{2}=13[/tex]
[tex]\\ \sf\longmapsto x+16=13(2)=26[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{26}{16}[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{13}{8}[/tex]
[tex]\\ \sf\longmapsto x=1.6\$[/tex]
[tex]\\ \sf\longmapsto Weekly allowance=13+7(1.6)[/tex]

It started at 62 degrees. What will the temperature be
in 16 hours? Please and Thank you !!
Answer: It will be 50º :)
Step-by-step explanation: 4 hours * 4 = 16, 3*4 = 12, 62- 12 = 50
Answer:
50 degrees
Step-by-step explanation:
16/4 = 4
4 * - 3 = - 12
62 - 12 = 50 degrees

The perimeter of an equilateral triangle is 3 (+ 5). The perimeter of a rectangle is 2 (2x - 3) + 2(2). If the perimeters of the two figures are equal, then what is the value of r?
Answer:
3.25
Step-by-step explanation:
Perimeter of triangle = 3(5) = 15 cm
Perimeter of rectangle = 2(2x - 3 + 4)
Perimeter = 2(2x + 1)
Perimeter = 4x + 2
4x + 2 = 15
4x = 15 - 2
4x = 13
x = 13/4
x = 3.25

Find the equation of the line that passes through the point
(4, 11) and is perpendicular to y= 4/3x + 7
Answer:
y = -3/4x + 14
Step-by-step explanation:
The slope of a perpendicular line is the opposite reciprocal of the original line.
4/3x -> -3/4x
Now we need to find the y-intercept and we can do that by using the slope intercept form expression [ y = mx + b ].
11 = -3/4(4) + b
11 = -3 + b
14 = b
Put everything we know and solved for back into the expression.
y = -3/4x + 14
Best of Luck!

Two numbers, a and b, are each greater than zero, and the square root of a is equal to the cube root of b. For what value of x is a^(2x-1) equal to b ?
Answer:
x = 1/2
Step by step explanation:
Two numbers a and b are each greater than zero.
i.e a > 0 and b > 0
And;
[tex] \sqrt{a} \: = \: \sqrt[3]{b} [/tex]
Since the square root of a is equal to cube root of b then,
a = b = 1
[tex] {a}^{2x \: - \: 1} \: = \: b[/tex]
[tex] {1}^{2x \: - \: 1} = {1}^{0} [/tex]
2x - 1 = 0
x = 1/2
Two numbers are 'a' and 'b'.
And a > 0, b > 0
[tex]\sqrt{a}=\sqrt[3]{b}[/tex]
[tex]a^{\frac{1}{2} }=b^{\frac{1}{3}}[/tex]
[tex]a=(b)^{\frac{2}{3} }[/tex]
We have to find the value of [tex]x[/tex] if [tex]a^{2x-1}=b[/tex],
By substituting the value of [tex]a[/tex] in the given expression,
[tex](b^{\frac{2}{3}})^{2x-1}=b[/tex]
Now use the laws of exponents,
[tex]b^{\frac{2}{3}(2x-1)}=b[/tex] [Since, [tex](a^m)^n= a^{mn}[/tex]]
By comparing the exponents on both the sides,
[tex]\frac{2}{3}(2x-1)=1[/tex]
[tex]2(2x-1)=3[/tex]
[tex]4x-2=3[/tex]
[tex]4x=5[/tex]
[tex]x=\frac{5}{4}[/tex]
[tex]x=1.25[/tex]

6. One angle of a triangle is 20 degrees. The second angle-s measurement is four times the
third. What is the measure of the third angle?
Answer:
32
Step-by-step explanation:
first angle is 20, let third angle be x, therefore second angle equals 4x; angle in a triangle is 180, so 4x+x+20=180; 5x=160; x=32

Answer:
27
Step-by-step explanation:
Evaluating this expression according to the order of operations is a straightforward calculator problem.
= (81 ÷ 27)³ = 3³ = 27
__
You can also use the rules of exponents to simplify this before evaluating.
(a^b)^c = a^(bc)
(a^b)/(a^c) = a^(b-c)
__
= ((3²)² ÷ 3³)³ = (3⁴ ÷ 3³)³ = (3¹)³ = 3³ = 27
Mr. Santiago can buy light fixtures in packages of 12 and light bulbs in packages of 9. He bought the fewest number of light fixtures and light bulbs so that there is exactly one bulb per fixture with none left over.
How many packages of light fixtures and how many packages of light bulbs did Mr. Santiago buy?
I WILL GIVE BRANLIEST PLEASE HELP AND RIGHT ANSWER
Answer:
3 and 4 packagesStep-by-step explanation:
We need to find the LCM of 12 and 9.
9 = 3*312 = 2*2*3Their LCM is:
LCM(12, 9) = 2*2*3*3 = 36Number of light fixtures and light bulbs is 36.
Number of packages will be:
36/12 = 3 and36/9 = 4 respectively.Step-by-step explanation:
First finding LCM of 9 and 12
9 = 3 × 3
12 = 2 × 2 × 3
LCM = 3 × 2 × 2 × 3
LCM = 36
Now,
No. of light fixtures = 36/12 = 3
No. of light bulb = 48/12 = 4
