Answer:

Step-by-step explanation:

question no 3

In complementary angles , sum of two angles is 90 degree. so here,

angle A + angle B = 90 degree

angle A is given i.e 11 degree . substitute the value of A

11 degree + angle B= 90 degree

angle B = (90 -11) degree

angle B = 79 degree

question no 4

In supplementary angles , sum of two angles is 180 degree so here,

angle A + angle B = 180 degree

angle A is given i.e 149 degree . substitute the value of angle A

149 degree + angle B = 180 degree

angle B = (180 - 149) degree

angle B = 31 degree

Solve for x:<br> 600<br> x + 124<br> Just enter the number.

Kryger [21]

Answer: -4. Reasoning: We are trying to get the angle of both lines to equal 180. If you add 60+124 together to see how much we have currently, your answer comes up to 184. That’s 4 over what we need, therefore, -4 would be needed to bring the current amount back down to 180.

Simplify (x^6)^2 • x^3

givi [52]

Answer:

x^15

Step-by-step explanation:

Recall these rules of exponents:

(a^m)^n = a^mn

a^m • a^n = a^(m + n)

(x^6)² • x³ = x^(2 • 6) • x³ = x^12 • x³ = x^(12 + 3) = x^15

What is 4 multiplied by 5 7/9 as a mixed number or fraction

Andrei [34K]

The answer is 23 and 1÷9

First you multiply 4 by 5 and wind up with 20
Then you multiply four by 7÷9.
That gets you 28÷9
You take out all the nines you can from 28, three in this case.
That gets you 27÷9 + 1÷9
Your total thing is 20+27÷9+1÷9
That equals 20+3+1÷9
That equals 23 and 1÷9

-4rover4+5rover3 please help me

Alchen [17]

$Solution, \frac{-4r}{4}+\frac{5r}{3}=\frac{2r}{3}$

$Steps:$

$\frac{-4r}{4}+\frac{5r}{3}$

$\frac{-4r}{4},\\\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b},\\-\frac{4r}{4},\\\mathrm{Divide\:the\:numbers:}\:\frac{4}{4}=1,\\-r,\\-r+\frac{5r}{3}$

$\mathrm{Convert\:element\:to\:fraction}:\quad \:r=\frac{r3}{3},\\\frac{5r}{3}-\frac{r\cdot \:3}{3}$

$\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c},\\\frac{5r-r\cdot \:3}{3}$

$5r-r\cdot \:3,\\\mathrm{Add\:similar\:elements:}\:5r-3r=2r,\\\frac{2r}{3}$

$The\:Correct\:Answer\:Is\:\frac{2r}{3}$

$Hope\:This\:Helps!!!$
