Answer:
x = 7
Step-by-step explanation:
3x - 9 = 12
3x = 12 + 9
3x = 21
x = 21 ÷ 3
x = 7
Answer:

Step-by-step explanation:
180-46= 134º
134/2= 67º
Step-by-step explanation:(3500)(0.07)=250
In question said 3500 invested at 7% that's why you have to multiply
Answer:
#4: -18xy^3z * sqrt(z)
#5: 24xy^3 * sqrt 3(x^2)
Step-by-step explanation:
#4: -2*sqrt(9^2 * x^2 * y^2 * y^2 * y^2 * z^2 * z)
You can cancel if there is a number sqaured
-2 * 9 * x * y * y * y * z * sqrt(z)
-18xy^3z * sqrt(z)
#5: 6 * sqrt 3( 4^3 * x^3 * x^2 * (y^3)^3 )
You can cancel if the number is cubed.
6 * 4 * x * y^3 * sqrt 3( x^2 )
24xy^3 * sqrt 3(x^2)
Answer:
a. Short-Sleeve = 35
b. Long-Sleeve = 27
Step-by-step explanation:
Given data:
Total shirts sold = 62
short sleeved cost = 11 each
Long sleeved cost = 17 each
Total receipts = 844
<em>Let the count of short sleeved be X and Let the count of long sleeved be Y</em>
X + Y = 62 <em>(equation 1) from the total shirts sold</em>
11X + 17Y = 844 <em>(equation 2) from the total receipts</em>
<em>From equation 1</em> X = 62 - Y <em>(Equation 3)</em>
<em>Substituting equation 3 into equation 2</em>
11(62 - Y) +17Y = 844
682 -11Y + 17Y = 844
-11Y + 17Y = 844-682
6Y = 162
Therefore Y = 27
<em>Substituting Y into equation 3</em>
X = 62 - Y
X = 62 - 27
X = 35
