Answer:
The coefficient of x is 6
Step-by-step explanation:
The two expressions are
(x)=-5x+1f(x)=−5x+1
and .
f(x)=6f(x)=6.
The sum of the two expressions is
f(x)=-5x+1f(x)=−5x+1(f(x)=6f(x)=6.)
When we group like terms the expression will be,
f(x)=-5x+1f(x)=−5x+1(f(x)=6f(x)=6.)=f(x)=-5x+1f(x)=−5x+1(f(x)=6f(x)=6.)
When we simplify the expression will now be
f−5x+1(f(x)=6.)
The coefficient of x is the constant behind x in the expression.
The coefficient of x is 3 therefore the answer is 3 .

Answer:
Step-by-step explanation:
given :
y = 120 degree
z = 57 degree
angle x = ?
first lets find angle c in triangle BDC
<h3>angle c + z = y (sum of two interior opposite angle is equal to the exterior angle formed)</h3>
angle C + 57 = 120
angle C = 120 -57
angle C = 63 degree
Now lets find angle B in triangle BDC
angle B + angle C + z = 180 degree (sum of interior angles of a triangle)
angle B + 63 + 57 = 180
angle B + 120 = 180
angle B = 180 - 120
angle B = 60 degree
now for angle x
angle B + z = angle x (sum of two interior opposite angles is equal to the exterior angle formed)
60 + 57 = x
117 = x

Answer:
120 coats, 200 shirts, 180 slacks
Step-by-step explanation:
If we let c, s, p represent quantities of coats, shirts, pants, respectively, then the total number of minutes required for cutting, sewing, and packaging can be expressed by ...
20c +15s +10p = 7200
60c +30s +24p = 17520
5c +12s +6p = 4080
These equations can be written in "augmented matrix" form and submitted to your friendly local matrix solver (online or on your calculator). You would ask for "reduced row-echelon form". The calculator function that accomplishes this is often called RREF. The matrix and result are ...
This means production should be of ...

Answer:
66.67%
Step-by-step explanation:
They do not say that I estimate a value of 350 chips but in reality there were 210 chips in total, we have that the error formula is:
Percentage error (%) = (estimated value - actual value) / actual value × 100 (in absolute value)
replacing:
Percentage error (%) = | 350 - 210 | / 210 × 100
Percentage error (%) = 140/210 * 100
Percentage error (%) = 66.67
Which means that the percentage error is 66.67%
Answer:
6. b. 50
7. d. 12
Step-by-step explanation:
6. 80% is equal to 0.8.
0.8x =40.
Divide 0.8 by 40 to get x.
x=50.
7. If he needs 3 eggs for 30 cookies, we divide 120 by 30 to get 4.
We multiply 4*3 to find the total amount of eggs needed.
4*3= 12
