The sum of two numbers is 48. The larger number is 7 less than four times the smaller number. Find the numbers.
Bumek [7]
Answer: x = 37 and y = 11

Explanation:

Let x be the bigger number
Let y be the smaller number

x + y = 48

But x is 7 less 4 times the smaller number.

=> x = 4y - 7
Substitute this value of x:

4y - 7 + y = 48
5y = 48 + 7
5y = 55
y = 11

Substitute the value of y in to the equation:

x + 11 = 48
x = 48 - 11
x = 37

Therefore, x = 37 and y = 11

In the diagram shown, M, N and P are collinear and QM=QN as shown. If mMQN = 48" and
fredd [130]

Answer/Step-by-step explanation:

Let's find the measure of the angles of ∆QNP.

∆QMN is am isosceles ∆, because it has two equal sides. Therefore, its base angles would be the same. Thus:

m<MNQ = ½(180 - 48) (one of the base angles of ∆QMN)

m<MNQ = ½(132) = 66°

Next, find m<QNP

m<QNP = 180° - m<MNQ (linear pair angles)

m<QNP = 180° - 66° (Substitution)

m<QNP = 114°

Next, find m<P

m<P = 180 - (m<QNP + m<PQN) (sum of ∆)

m<P = 180 - (114 + 33)

m<P = 180 - 147

m<P = 33°

Thus, in ∆QNP, there are two equal angles, namely, <P and <PQN.

An isosceles ∆ had two equal base angles. Therefore, ∆QNP must be an isosceles ∆.

You buy a new video game for 59.99 the sales tax is 8% what is the total cost for the game including sales tax?
astraxan [27]
Well first of all the sales tax is 4.80 so now you add them.So 59.99 + 4.80 is 64.79.

But if you're supposed to round then you would just add 60.00 + 4.80 is 64.80.

Hope this helps :D 

If I'm wrong I'm sorry D:
