3 0

Answer:

212

Step-by-step explanation:

The given expression is 3m^2+2p^2-15

Substituting m = 3 and p = 10 in the expression

3(3)^2+2(10)^2-15

Now, simplify this expression

3\times9+2\times100-15\\\\=27+200-15\\\\=227-15\\\\=212

Therefore, the value of the expression is 212.

Third option is correct.

11 more than y is equal to 7
fomenos

We first have to come up with an equation that satisfies this. The equation is y+11=7.

Then we subtract 11 from both sides. y+11-11=7-11.

Then we get the answer y=-4.

David, Stephen and June share £96 in a ratio 2:3:3. How much money does each person get
AveGali [126]

Answer:

<u>David gets £24, Stephen gets £36, and June gets £36.</u>

Step-by-step explanation:

Firstly, add the ratio values together.

2:3:3  ⇒  2 + 3 + 3 = 8

Next, divide £96 (your total) by 8.

£96 ÷ 8 = £12

Now, we have the number of pounds for 1 value.

Multiply 12 by each ratio value.

<u>12 × </u><u>2</u> : <u>12 × </u><u>3</u> : <u>12 × </u><u>3</u>

= 24:36:36

Therefore, David gets £24, Stephen gets £36, and June gets £36.

Allison plays basketball and last season she made a total of 87 shots (two- or three- point shots). Her points total was 191. Ho
yarga [219]

Answer:

17

Step-by-step explanation:

Let the number of 2 point shots be t.

Let the number of 3 point shots be h.

Allison made 87 shots and scored 191 total points. This implies two things:

t + h = 87 ________(1)

2t + 3h = 191 ______(2)

Let us eliminate t by multiplying (1) by 2 and subtracting from (2):

=> 2t + 3h = 191

 -  <u>2t + 2h = 174</u>

     <u>          h  = 17 </u>

<u />

Therefore, she made 17 three point shots.
