Answer:
3/2 x +1 = 5/4x - 5
3/2 x+1 =5/4
x−5
Step 1: Subtract 5/4x from both sides.
3/2 x+1−5/4
x=5
4x−5−5/4x
1/4x+1=−5
Step 2: Subtract 1 from both sides.
1/4x+1−1=−5−1
1/4
x=−6
Step 3: Multiply both sides by 4.
4*(1/4x)=(4)*(−6)
x=−24 Mary has 24 shells
Answer:
-x=−24
x = 24 shells
Step-by-step explanation:
1. 2 3/4 x 16 = 44 + 6 = 50 shells x= 16
2 3/4 x 24 = 66 + 6 = 72 x = 24
We see the side workings in bold as if Mary has 24 and Nancy has 1x more
Then Nancy 24+24 = 48 where Gracie 5 x 24 = 120 and we have 72-48 = 24 and 120-72 = 48 being the same as Nancy. You can ignore or check the rest in explanation.
2 3/4 x 18 = 49 1/2 + 6 = 55 1/2 x= 18
2. 2 3/4 x 16 = 44 -4 = 40 shells x = 16 2 3/4 x 24 = 66 - 4 = 62 x = 24
2 3/4 x 18 = 49 1/2 - 4 = 45 1/2 x = 18
3. 2 3/4 x 16 = 44 + 4 = 48 shells x = 16 2 3/4 x 24 = 66 + 4 = 70 x = 24
2 3/4 x 18 = 49 1/2 + 4 =53 1/2 x = 18
Answer:
The standard form of line is
Step-by-step explanation:
we are given a line
slope=3
so,
y-intercept of -2
so,
now, we can use slope-intercept form of line
now, we can plug values
we can write it in standard form of line
we can subtract both sides by 3x
So, the standard form of line is
X = 5y
5y = X
y = X/5
y = 1/5 X + 0
So the y-intercept is 0, meaning that both intercepts are the same, at (0,0). However, there is a slope in the equation (1/5), meaning the rise is 1, and the run is 5, so the next point on the line is (5, 1), and then (10,2), and so on. Hope this helps!

Answer:
<u>The correct answer is D. 54 ÷ 18 = c</u>
Step-by-step explanation:
Let's review the information given to us to answer the question correctly:
Number of cookies Mrs. Myles has to give to the students = 54
Number of students in Mrs. Myles class = 18
2. Write a number sentence using the variable c to represent the number of cookies each student gets.
c = Number of cookies Mrs. Myles has to give to the students/Number of students in Mrs. Myles class
Replacing with the real values, we have:
c = 54/18
<u>The correct answer is D. 54 ÷ 18 = c</u>
