15×0.8= 12
you're multiplying the total number of questions with the score as a decimal
Wait what does the question say 4 me it's blurry
Answer:
After finding the solution of given equations by elimination method
-3x-3y=12
-9x+3y=-24
we get the value of x=1 and y= -5
Step-by-step explanation:
is eq A
is eq B
To find out value of x and y we will use elimination method
To find value of x add eq A and eq B

Now to find value of y put x=1 in eq A

so the value of
x= 1
and
y= -5
For checking the solution
putting value of x and y in eq A

Hence proved
Putiing value of x and y in eq B

Hence proved

Answer:
78°
Step-by-step explanation:
Corresponding parts of congruent triangles are congruent, so m∠S = m∠N, which is 78°.
Answer:
the actual sales be $31,132
Step-by-step explanation:
The computation of the actual sales is as follows:
Let us suppose the actual sales be x
Now the sales tax be 0.06x
Now the total sales would be
x + 0.06x = $33,000
1.06x = $33,000
x = $33,000 ÷ 1.06
= $31,132
hence, the actual sales be $31,132
The same is to be considered by applying the above equation
