Hello from MrBillDoesMath!

Answer:

Discussion:

Given: measure angle STQ = 7x + 55. But, as shown, STQ is a right angle so

7x + 55 = 90 => subtract 55 from each side

7x = 90 -55 = 35 => divide each side by 7

x = 35/7 = 5

Since RS = (x+1) + (2x-1) where x = 5.

RS = (5 + 1) + (2*5 -1)

= 6 + 9

= 15

I don't know what choice the answer is as your diagram only shows Choice A

Thank you,

MrB

Solve the system of inequalities to decide if the point (-3,2) is part of the solution; y<=-4x-3, +8y>=7

inna [77]

Answer:

$(x,y) = (-3,2)$ is a solution

Step-by-step explanation:

Given

$y \le -4x + 3$

$x + 8y \ge 7$

Required

Determine if $(x,y) = (-3,2)$ is a solution

$y \le -4x + 3$ becomes

$2 \le -4 * -3 + 3$

$2 \le 15$ --- this is true

$x + 8y \ge 7$

$-3+ 8 * 2 \ge 7$

$13 \ge 7$ --- this is also true

Hence,

$(x,y) = (-3,2)$ is a solution

tatuchka [14]

To find the total cost of Roland's purchases, you will add $382 plus $12 plus $16.14 together to find the total spent.

$410.14.

Next will be to calculate the new price based on the sales tax rate. To do this you will multiply the cost by 1.0825. This includes everything you paid and the sales tax

410.14 x 1.0825 = $443.98

Roland's total price was $443.98.

Kylie buys cranberries and raspberries in the ratio of 8:9 to prepare mock tails. If she buys 64 ounces of cranberries what is t

xeze [42]

Answer: 136 ounces

Step-by-step explanation:

Given: The ratio of cranberries and raspberries is 8:9 .

Let quantity of cranberries= 8x , quantity of raspberries = 9x

If quantity of cranberries = 64 ounces

$\Rightarrow\ 8x=64\\\\\Rightarrow\ x=\dfrac{64}{8}\\\\\Rightarrow\ x=8$

Quantity of raspberries = 9(8) = 72 ounces

Total quantity = 64 ounces + 72 ounces = 136 ounces

Hence, the total weight of berries purchased= 136 ounces
