Answer:
0.27
Step-by-step explanation:
Red marbles = 4
Yellow marbles = 16
Purple marbles = 5
Blue marbles = 16
Green marbles = 10
Total marbles
= 4 + 16 + 5 + 16 + 10
= 51
Red and Green marbles
= 4 + 10
= 14
P(Red or green marbles)
= 14/51
= 0.27
Answer:
10. X = 2.75
11. X = 1.61
Hey there, I have the steps listed below but what is the problem asking, I cannot solve it unless it explains the problem. Thank you!
Step-by-step explanation:
10. 5x + 10 + 11x + 2 = 56
16x + 12 = 56
16/16x = 44/16
X = 2.75
11. -1 + 8x + 18x + 5 = 46
26x + 4 = 46
26/26x = 42/26
X = 1.61

Answer:
<span>−84</span>
Explanation:
Let x be the unknown number.
From the queston we can form the equation
<span><span>x<span>(−7)</span></span>−2=10</span>
Move <span>−2</span> to the right hand side
<span><span><span>x<span>(−7)</span></span>=10+2</span><span><span>x<span>(−7)</span></span>=12</span></span>
Multiply both sides by <span>−7</span> to get the unkonwn no.
<span><span><span>−7</span>⋅<span>x<span>(−7)</span></span>=12⋅<span>(−7)</span></span><span>
x=−84</span></span>
Hope this helps
Answer: 3 11/20
explanation: change 3 3/4 to a mixed number which is 15/4 then get a common denominator which is 75/20 - 4/20 then subtract and get 71/20 and then change to a mixed number and simplify to get 3 11/20
