Sorry but i only know the answer for the 1st question.
--------------------------
If the angles are complementary they measure 90°.
1st find half of 90
which is 45.
Find 4 more than 45.
which is 49°
then subtract 90-49=41
so the measurement of the 2 angles are
49 and 41
Hope it helps!!

Y=-5x + 22<br> -2x - 8y = 14
laiz [17]

Step-by-step explanation:

Put the value y.

-2x-8(-5x+22)=14

-2x+40x-176= 14

38x-176 =14

38x = 190

x=5

Now put the value of X to find Y

Y= -5(5)+22= -25+22 = -3

=>X=. 5

=>Y= -3

A 30cm board is cut down to be 25.5 cm. What is the percent decrease in length?
zmey [24]
Okie, so percent decrease is the amount loss divided by the original number and multiplied by 100 to find the percent. This is because you are finding the amount loss in terms of the total amount - percent basically.
The amount loss : 4 feet
4 feet/ 12 feet = .3333 (ratio of how much cut) multiply by 100 --> 33.3% decrease. From 12 feet to 8 feet is a 33.3 % decrease. I hope this helps :-)

7x + 2y = 4
Vinil7 [7]

7x + 2(x + 1) = 4 \\ 7x + 2x + 2 = 4 \\ 9x  + 2 = 4 \\ 9x = 2 \\ x =  \frac{2}{9}  \\  \\ y =  \frac{2}{9}  + 1 =  \frac{11}{9}  \\ ( \frac{2}{9}  \:  \frac{11}{9} )

Maria invested $450 in a savings account and earned $126 in interest at the end of 7 years.
Brut [27]
The interest rate is B. 4%

Given:
Principal = 450
Interest = 126
term = 7 
rate = ?

Simple Interest is computed by multiplying the Principal, rate, and term.

Interest = P × r × t

126 = 450 × r × 7
126 = 3150r
r = 126/3150
r = 0.04 x 100% = 4%

To check:

I = 450 
× 0.04 x 7
I = 18 × 7
I = 126
