Evaluate 7xy ÷ w + 4z when w = 10,x = 2,y = 5, and z = 9

1 answer:

4 0

First,, we need to insert the numbers in before we can start solving. This will change the expression to the following:
7(2)(5) ÷ 10 + 4(9)
We are first going to begin solving this by calculating the expression 7 × 2 × 5 ÷ 10. We can start this solving this by multiplying 2 by 5.
7 × 10 ÷ 10
Any expression divided by itself equals 1,, so the expression changes to:
7 × 1
Any expression multiplied by 1 remains the same,, so add 7 back into the equation.
7 + 4 × 9
Multiply the numbers together.
7 + 36
Lastly,, add the numbers together to find your final answer.

Let me know if you have any further questions.

Write an algebraic expression that represents each purchase.

Svetradugi [14.3K]

Answer: Both answers will be

$15x+18$

Step-by-step explanation:

Since we have given that

Cost of soccer balls = $15

Cost of baseball = $6

Cost of sweat socks = $5

a) Mr. Tonkery bought x number of soccer balls and 3 base balls .

So, our algebraic expression will be

$15x+3\times 6\\\\=15x+18$

b) Dennis, Eddie and Felix are on a base ball team. They each bought a baseball and x pair of sweat socks .

Since there are 3 members in a base ball team ,

Number of base ball they will purchase is given by

$3\times 6=18$

Number of sweat socks they will bought is given by

$5\times x\times 3=15x$

Total number they will purchase is given by

$15x+18$

Hence, both answers will be

$15x+18$

What are the answers for question 1 and 2??

xeze [42]

Answer:

1) Answer: 3) $~~x = -3 \pm \sqrt{7}$

2) Answer: 3) 2 and -6

Step-by-step explanation:

$(x + 3)^2 = 7$

$x + 3 = \pm \sqrt{7}$

$x = -3 \pm \sqrt{7}$

Answer: $3)~~x = -3 \pm \sqrt{7}$

$2(x + 2)^2 - 4 = 28$

$2(x + 2)^2 = 32$

$(x + 2)^2 = 16$

$x + 2 = \pm \sqrt{16}$

$x + 2 = \pm 4$

$x + 2 = 4$ or $x + 2 = -4$

$x = 2$ or $x = -6$

Answer: x = 2 or x = -6

A baker can make 120 cupcakes in 2 hours. At that rate, how many cupcakes can he make in 3.5 hours? *

Valentin [98]

Answer:

210

Step-by-step explanation:

first I took 120 and divided by four to show how many cupcakes he can make in thirty minutes (.5 of an hour). this was 30. the reason we divided by four is because in two hours theres four halves.

120÷4=30 for half an hour

30x2=60 this is how many cupcakes he can make in one hour

since we already know how many he makes in two hours we're going to use that

120+60=180 (three hours)

120+60=180 (three hours)180+30 (half an hour) =210
