5*147/65 ≈ 12 studentsAnswer:
12 studentsStep-by-step explanation:
147 maintained 65% attendance for the 1st 4 weeks
the goal is 70% on the next 4 weeks
ratio and proportion:
147 students = x
65 70
65 (x) = 147 (70)
x = 10,290
65
x ≈ 159 students
therefore, the number of students would need to attend
daily for the next 4 weeks is
= 159 - 147
= 12 students

How to solve 2y-6x=2
Please provide steps only. lol
Answer:
y-x = -6
Step-by-step explanation:
Ok so you have 2y-6x=2
step 1: when you add 6 to 6x it cancels out the 6 then subtract 2 by six and get 2y-x=-4.
step 2: when you add 2 to 2y it cancels out the 2 then subtract -4 by two and get your answer.

Help please problem is worded weird
Answer:100
Step-by-step explanation:
Expand
x = 150 - 0.5x
Add 0.5x to both sides
x + 0.5x = 150
Simplify x + 0.5x to 1.5x
1.5x = 150
Divide both sides by 1.5
x = 150/1.5
Simplify 150/1.5 to 100
x = 100
Answer: the correct awnser is 100
Step-by-step explanation:
plz help i cant slove it
Answer:x=30
Step-by-step explanation:
So first you have to find x so add all your sides together:
Equation: 45+2x+0.5x+x=150
Combine like terms: 45+3.5x=150
Subtract 45 from -45 -45
both sides: 3.5x=105
Then divide by 3.5: x=30
Now that you have your x substitute it in:
2(30)=60
0.5(30)=15
and the last one is x=30
And there you have all your sides! If you wanna check it just add up all the sides and it should equal 150.

$50

$35
withdrawal -$70
withdrawal -$50
Answer:
5
Step-by-step explanation:
The account balance after transactions will be $90.
What is Addition?
A process of combining two or more numbers is called addition.
Given that;
The account started with a balance of $125 and
deposit $50,
deposit $35
withdrawal -$70
withdrawal -$50
Now,
Deposit in account means to add the amount and withdrawal means to remove money from account.
Since, The account started with a balance of $125.
After deposit $50,
The account balance = $125 + $50 = $175
Again after deposit $35;
The account balance = $175 + $35 = $210
After withdrawal -$70;
The account balance = $210 - $70 = $140
Again after withdrawal -$50;
The account balance = $140 - $50 = $90
Thus, The account balance after transactions will be $90.

Can someone explain how to answer this
Answer:
q= -ck+dp/
-k+d
Step-by-step explanation:
Step 1:
Multiply both sides by p.
dp=ck−kq+pq
Step 2:
Flip the equation.
ck−kq+pq=dp
Step 3:
Add -ck to both sides.
−kq+pq=−ck+dp
Step 4:
Factor out variable q.
q(−k+p)=−ck+dp
Step 5:
Divide both sides by -k+p.
q= -ck+dp/
-k+d

Evaluate the following expression when x=14. X^2+5x+11
Answer:
277
Step-by-step explanation:
14^2+5(14)+11=
196+70+11=
277
Start by substituting 14 in for x everywhere that x appears in the problem.
So we have (14)² + 5(14) + 11.
Remember that PEMDAS tells you to deal
with your exponents before multiplying.
So you must square the 14 to get 196.
So we have 196 + 5(14) + 11.
Now multiply 5(14) to get 70.
So we have 196 + 70 + 11.
Now we can simply add to get 277.
2h = W-3p
(solve for p)
Answer:
p = (2h-W)/-3
Step-by-step explanation:
2h - W = -3p
divide both sides by -3
(2h-W)/-3 = p
The value of p is w/3 - 2h/3.
What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S
Given:
2h = W-3p
For p move w
2h - w = -3p
Now, divide both side by 3
2h/3 - w/3 = -3p/3
2h/3 - w/3 = -p
p= w/3 - 2h/3
Hence, the value of p is w/3 - 2h/3.
