Answer:

Step-by-step explanation:

To convert a decimal into a percent, you multiply by 100 and then put the percent sign on the end. Here are some examples:

0.32 x 100 = 32%

9.7 x 100 = 970%

0.083 x 100 = 8.3%

once you get the hang of it, it’s pretty easy! :]

Solve the following system of equations.What is one x-value of a solution? f(x) = x² + 7x- 24 g(x) = -3x - 40 x = 4 x = -3 x = 3

oksian1 [2.3K]

For the given set of equations, the values of x = -8 and x = -2.

We have, f(x) = x² + 7x- 24 and g(x) = -3x - 40

An Equation is an algebraic statement that shows that two quantities are equal.

For one x-value of a solution,

We equate both the given functions,

Thus, f(x) = g(x)

x² + 7x- 24 = -3x - 40

$x^{2}$ +7x + 3x -24 + 40 = 0

$x^{2}$ +10x + 16 =0

$x^{2}$ + 8x + 2x +16 =0

x(x+8) + 2(x +8) =0

(x+8) (x+2) = 0

x = -8 and x = -2

Hence, Concluding, we have x = -8 and x = -2

HELLO EVERYONE IT WOULD BE GREAT IF YOU CAN HELP ME IM ABOUT TO FAIL MY CLASS

MrMuchimi

Well we first need to add up all the purchases, 2 sandwiches are 6.86 each so by multiplying that we get 13.72. Next are the burgers, 3.44 x 4 is 13.76. We don’t need to multiply fries since there’s only one, so that’s just 3.19. Finally there are 4 drinks for 1.52 which gives us 6.08. We need to add these prices all together to get the total. 13.72 + 13.76 + 3.19 + 6.08 = 36.75. In order to find ten percent we multiply 36.75 by .10 which gives us 3.675. Double of 3.675 is 7.35. The price 13.72 (14 rounded) needs to be added with the tax 3.675 (4 rounded) and once again add 7.35. All together we get 25. Are there no other answer choices? Unless I did something wrong I’m sure this is right

Andrea is at the grocery store buying fruit for a smoothie stand. She needs 7 boxes of raspberries for every 5 bunches of banana

Degger [83]

Answer:

The greatest number of bunches of bananas that Andrea can buy is 15 and the greatest number of boxes of raspberries that Andrea can buy is 21 to maintain the ratio 7:5

Step-by-step explanation:

Let

x ---->the greatest number of boxes of raspberries that Andrea can buy

y ---->the greatest number of bunches of bananas that Andrea can buy

we know that

$100\%+8\%=106\%=108/100=1.08$ ---> sales tax

$\frac{x}{y} =\frac{7}{5}$

$x=\frac{7}{5}y$ ----> equation A

$1.08[2.50x+3.00y]\leq 135$ ----> inequality B

substitute equation A in the inequality B

$1.08[2.50(\frac{7}{5}y)+3.00y]\leq 135$

solve for y

Multiply by 5 both sides to remove the fraction

$18.9y+16.2y\leq 675$

$35.1y\leq 675$

$y\leq 19.23$

The maximum value of y is 19

Find the value of x

replace the value of y in equation A until you get an integer value that satisfies the ratio 7:5

For y=19

$x=\frac{7}{5}(19)$

$x=26.6$

For y=18

$x=\frac{7}{5}(18)$

$x=25.2$

For y=17

$x=\frac{7}{5}(17)$

$x=23.8$

For y=16

$x=\frac{7}{5}(16)$

$x=22.4$

For y=15

$x=\frac{7}{5}(15)$

$x=21$

therefore

The greatest number of of bunches of bananas that Andrea can buy is 15 and the greatest number of boxes of raspberries that Andrea can buy is 21 to maintain the ratio 7:5

Verify the inequality B

$1.08[2.50(21)+3.00(15)]\leq 135$
