Answer:
z= 1
Step-by-step explanation:
Rewrite the equation as
15(z−1/5)z12
Apply the distributive property
15z+15(−1/5)= 12
Cancel the common factor of 5
15z+3*−1= 12
Multiply 3 by −1
15z−3= 12
Divide each term by 15 and simplify
5z−1 = 4
Since the expression on each side of the equation has the same denominator, the numerators must be equal
5z−1= 4
Move all terms not containing z to the right side of the equation
5z= 5
Divide each term by 5 and simplify
z = 1
We know that d equals the dollar amount needed to buy one hundred seventy-six tickets.
Fill in the proportion using the ratios highlighted in the table.
Answer:
d = 110
Step-by-step explanation:
From the table of values given, we know that the ratio of dollar to ticket is 5 : 8.
Therefore, the amount of dollar to 176 dollars would be d : 176.
Using this proportion, we can find the value of d as shown below:
5 : 8 = d : 176
[tex] \frac{5}{8} = \frac{d}{176} [/tex]
Multiply both sides by 176
[tex] \frac{5}{8}*176 = \frac{d}{176}*176 [/tex]
[tex] \frac{5*176}{8} = d [/tex]
[tex] \frac{880}{8} = d [/tex]
[tex] 110 = d [/tex]
d = 110
Answer: The answer is d simply d
Step-by-step explanation: dont get confused... The correct answer is d

7. What number is 32% of 79?
A.n= 32.79: 2.528
B.32 = n. 79: 0.4
C.79=n.0.32: 246.9
D.n-0.32.79; 25.3
Answer:
If they're asking you to round, I'll choose D just because 25.28 is 25.3 rounded to the nearest tenth.
Step-by-step explanation:
79/x=100/32
(79/x)*x=(100/32)*x - we multiply both sides of the equation by x
79=3.125*x - we divide both sides of the equation by (3.125) to get x
79/3.125=x
25.28=x
x=25.28

Answer:
x = 10, x = 124
Step-by-step explanation:
(5)
Since Δ JKL is isosceles then the base angles are congruent, that is
∠ LJK = ∠ LJG = 80° , thus
∠ JLK = 180 - (80 + 80) = 180 - 160 = 20
x = 20 ÷ 2 = 10
(6)
Since Δ PQR is equilateral, then each of its angles = 60°
∠QRS = 60° - 32° = 28°
Since Δ SQR is isosceles then base angles are congruent, then
∠ SQR = ∠ QRS = 28 , thus
x = 180 - (28 + 28) = 180 - 56 = 124
answer :
x = 10, x = 124

Solve for y
a. 4x + 5y = 25
Answer:
y = -4/5x + 5
Step-by-step explanation:
In order to solve for y, we need to isolate the variable. First, let's subtract 4x on each side. After doing said step, we should now have this equation:
5y = -4x + 25
Next, we need to divide 5 on each side, giving us this new equation:
y = -4/5x + 5

Kendall is making greeting cards, which she will sell by the box at an arts fair. She paid $40
for a booth at the fair, and the materials for each box of cards cost $5. She will sell the cards
for $10 per box of cards. At some point, she will sell enough cards so that her sales cover her
expenditures. How many cards will that take?
Answer:
9
Step-by-step explanation:
40 dollars due up front
10 dollars made per sale
5 dollars lost per creation
Realistically speaking she is only making a $5 profit per box she sells;
$5 used up for material cost, $10 made from sales -5+10= 5
To pay the $40 dollar for the booth she would need to make 9 sales with her current profit
40/5 = 9
