Answer:
x = -6/5 and x = 2
Step-by-step explanation:
y = -10x² + 8x + 24
0 = -2(5x+6)(x-2)
5x+6 = 0 x-2 = 0
5x = -6 x = 2
x = -6/5

The environmental club at Paul sells gum and candy bars as a fundraiser. One afternoon, they sold $200 worth of candy. They need to report how many of each item they sold for their club records. Maura knows that they sold 295 items that day. Candy bars sell for 75 cents, and gum sells for 50 cents. How many candy bars and gums did Paul sell?
Answer:
210 candy bars
85 gum
Step-by-step explanation:
$200=0.75cb+0.50gum
cb+gum=295
gum=295-cb
substitute
$200=0.75cb+0.50(295-cb)
$200=0.75cb+147.5-0.50cb
$200=0.25cb+147.5
0.25cb=52.5
cb=210
gum=295-210=85
How do you figure this out?
Let the red cat be represented by x.
Let the yellow cat be represented by y.
Let the white cat be represented by z.
Which means :
[tex] \tt (1) \: \frac{4}{5} (20x - 5)[/tex]
[tex]\tt = \frac{4}{5} \times 20x - \frac {4 }{5} \times 5[/tex]
[tex] \tt= \frac{80x}{5} - \frac{20}{5} [/tex]
[tex]\tt = 16x - 14[/tex]
Thus, the first statement is correct.
[tex]\tt(2) \: \frac{3}{5} ( \frac{1}{3} z - 10)[/tex]
[tex]\tt = \frac{3}{5} \times \frac{1}{3} z - \frac{3}{5} \times 10[/tex]
[tex]\tt = \frac{3}{15} z- \frac{30}{5} [/tex]
[tex]\tt = \frac{1}{5} z - 6[/tex]
Thus, the second statement is a lie.
[tex]\tt(3) \: \frac{1}{9} ( - 9y - 27x)[/tex]
[tex] \tt= \frac{1}{9} \times - 9y - \frac{1}{9} \times 27x[/tex]
[tex]\tt = \frac{ - 9}{ \: \: 9} y - \frac{27}{9} x[/tex]
[tex]\tt = (- y) - 3x[/tex]
Thus, the third statement is correct.
Therefore, the second one is a lie.
Answer:
Let the money with Miguel be x.
Then :
Money with Kira = x - 9
Money with Charlie = 4x
Total money in their wallet = $105
This can be written in an equation as :
= \tt \: x + x - 9 + 4x = 105=x+x−9+4x=105
= \tt2x + 4x - 9 = 105=2x+4x−9=105
= \tt 6x - 9 = 105=6x−9=105
= \tt6x = 105 + 9=6x=105+9
= \tt6x = 114=6x=114
= \tt x = \frac{114}{6}=x=
6
114
= \tt x = 19=x=19
Which means :
Money with Miguel = $19
Money with Kira :
= 19 - 9
Thus, Kira has $10 in her wallet.
Money with Charlie :
= 4 × 19
= 76
Thus, Charlie has $76 in his wallet.
Therefore,
Money with Kira = $10
Money with Charlie = $76
Money with Miguel = $19

Kayla is trying to run a certain number of miles by the end of the month. If Kayla is 90% of the way to achieving her goal and she has already run 27 miles, how many miles is she trying to run by the end of the month?
Answer:
30
Step-by-step explanation:
The total number of miles she runs at the end of the month or Kayla's target of the month is 30 miles.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Let's suppose that Kayla's target is x miles.
She has done 90% of x as 27 miles.
90% of x = 0.90x
0.90x = 27
x = 27/0.90 = 30 miles
Hence "The total number of miles she runs at the end of the month or Kayla's target of the month is 30 miles".

Write and exponential function in the form y=ab^x that goes through points (0,17) and (5,4131)
Answer:
[tex]y = 17(3^{x} )[/tex]
Step-by-step explanation:
When x = 0, y = 17 So, [tex]17 = kb^{0} = k(1) = k[/tex]
Now, [tex]y = 17b^{x}[/tex]
When x = 5, y = 4131 So, [tex]4131 = 17b^{5}[/tex]
[tex]b^{5} = 4131/17 = 243 = 3^{5}[/tex]
b = 3
Therefore, [tex]y = 17(3^{x} )[/tex]

Find the measurement indicated in each parallelogram.
Find angle T
Angle V is 14x+13 and angle T is 16x-3
I need help figuring out the angle of T through the equation
Answer:
m∡T = 125°
Step-by-step explanation:
opposite angles in a parallelogram are equal so you can set each expression for V and T equal to each other
14x + 13 = 16x - 3
13 = 2x - 3
16 = 2x
x = 8
∡T: 16(8) - 3
128 - 3 = 125°

Anu borrowed Rs 4000 from a bank at 7 % per annum for 2 years. She then lent this amount to Nidhi at 9 % per annum for the same period. How much did Anu gain in this transaction?
Step-by-step explanation:
p- 4000
r- 7
t-2years
SI- P×r×t/100
SI-4000×7×2/100
SI- 4000×14/100
SI- 56000/100
SI- 560
so anu give = p+ SI
= 4000+560
= 4560 ₹
p- 4000
r- 9
t-2 years
SI- P×r×t/100
SI- 4000×9×2/100
SI- 4000×18/100
SI- 72000/100
SI- 720
so nidhi give= p+SI
= 4000+720
= 4720

Lucas has a 39-foot-long rope. He uses all the rope to outline this T-shape in his backyard. All the angles in the figure are right angles. (Work out and answer number 13 and number 14, please.)
Answer:
Step-by-step explanation:
The area of a shape is the amount of space it can occupy, while the perimeter is the sum of its sides.
The value of x is 7.5 ftThe area of the shape is 57 square feetGiven that:
[tex]P = 39[/tex] --- the perimeter of the shape
The value of x
The perimeter is the sum of all sides.
So, we have:
[tex]P = x + x + 3.5 + 3.5 + 3 + 3 + 9 + (9 - 3.5 - 3.5)[/tex]
Substitute 39 for P
[tex]x + x + 3.5 + 3.5 + 3 + 3 + 9 + (9 - 3.5 - 3.5) = 39[/tex]
[tex]2x + 24 = 39[/tex]
Collect like terms
[tex]2x = -24 + 39[/tex]
[tex]2x = 15[/tex]
Divide through by 2
[tex]x = 7.5[/tex]
The area of the shape
The shape can be divided into two rectangles
A 9ft by 3ft rectangleA (9 - 3.5 - 3.5)ft by x ft rectangleSo, the area of the shape is:
[tex]Area = 9ft \times 3ft + (9 - 3.5 - 3.5)ft \times x ft[/tex]
[tex]Area = 27ft^2 + 2ft \times x ft[/tex]
Substitute [tex]x = 7.5[/tex]
[tex]Area = 27ft^2 + 2ft \times 15 ft[/tex]
[tex]Area = 27ft^2 + 30 ft^2[/tex]
[tex]Area = 57 ft^2[/tex]
Hence, the area of the shape is 57 square feet.
