barry has 18 more marbles than heidi.if barry has 92 marbles,write and solve an equation to determine the number of marbles heid
Basile [38]
N= Heidi's marbles
92 - n =18   (Barry's 92 marbles - whatever Heidi has = 18 marbles difference)

92 -n +n = 18 +n   (I added n to each side)
92 = 18+n    
 92 -18 = 18-18 + n   (I subtracted 18 from both sides)
74 = n    Heidi has 74 marbles

Help me please i’m struggling, u don’t have to explain

<h3>Answer:  10 cm  (choice A)</h3>

====================================================

Explanation:

One equation we could solve is

x/2.5 = 30/7.5

Note the x/2.5 has us dividing the vertical sides, while 30/7.5 is the same idea for the horizontal sides. The order is large over small. You could do small over large, but make sure you keep both sides consistent.

Solving for x leads to...

x/2.5 = 30/7.5

x*7.5 = 2.5*30

7.5x = 75

x = 75/7.5

x = 10  (choice A)

There are many other possible equations that lead to the same answer. One other possible equation is x/30 = 2.5/7.5

These proportions are possible due to the fact we have similar triangles.

How do you solve this equation step-by-step? (below)<br><br><br> 4a + 8 - 2a - 3 = 45
Rashid [163]

Answer:

a=20

Step-by-step explanation:

4a+8-2a-3=45

-8 on both sides

4a-2a-3=37

+3 on both sides

4a-2a=40

2a=40

a=20
