Answer:
sin44 = PR÷PQ = 0.694÷1 × X÷10 = X = 6.94
Answer:
Sure Amaya , the grouping is the parenthesis, right?
Step-by-step explanation:
so just add up.. the things outside of the parenthesis
-
* 4
so exponents come first in the order of what to do... right?
=16 okay , got that part, the next part is
16 * 4 = 64 okay got that part, now
- 64 is what is subtracted from the grouping , got it?
Answer:<span>x=<span><span><span><span><span>−10/</span>3 </span>y </span>+ <span>4z</span></span>+<span>40/<span>3</span></span></span></span>
Answer:
Let's solve your system of equations by elimination.
8x+9y=48;12x+5y=21
Steps:
Multiply the first equation by 5,and multiply the second equation by -9.
5(8x+9y=48)
−9(12x+5y=21)
Becomes:
40x+45y=240
−108x−45y=−189
Add these equations to eliminate y:
−68x=51
Then solve−68x=51for x:
−68x
/−68
=
51
/−68 (Divide both sides by -68)
x= −3
/4
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
8x+9y=48
Substitute
−3
/4
8x+9y=48:
8(
−3
/4
)+9y=48
9y−6=48 (Simplify both sides of the equation)
9y−6+6=48+6 (Add 6 to both sides)
9y=54
9y
/9 = 54
/9 (Divide both sides by 9) y=6
<em><u>Answer: x= −3
/4 and y=6</u></em>
Hope This Helps! Have A Nice Day!!
First, convert 4 feet into inches - 48 inches. Then, divide 48 by 14 to get 3.43, so he can have 3 14-inch long pieces. To get the left over out of a foot, take 14 x 3 to get 42, then subtract 42 from your original 48 inches to get 6 inches left, which is half of a foot.
