Let white marbles = x
Purple marbles = 5x + 2
Given:
x + 5x + 2 = 104
6x = 102
x = 17
Purple marbles = 5(17) + 2 = 85 + 2 = 87
Answer:
y=-3/2x+13
Step-by-step explanation:
7=-3/2(4)+b
7=-6+b
13=b
Answer: 88
Step-by-step explanation:
So we have 220:2.5, since 30 seconds is half a minute we can make that .5, so to get unit rate it’s formula is front divided by back,
220/2.5 = 88!
The third term, fourth term and tenth term are -1, -3, -15 respectively.

What is a sequence?</h3>
A sequence is a pattern of numbers in which successive terms differ by an constant term called the common difference or ratio.
Analysis:
For a sequence defined by the rule A(n) = 3 + (n-1)(-2)
Third term, n = 3
A(3) = 3 + (3-1)(-2) = -1
Fourth term, n = 4
A(4) = 3 + (4-1)(-2) = -3
Tenth term, n = 10
A(10) = 3 + (10-1)(-2) = -15
In conclusion, the third, fourth, tenth terms are -1, -3 and -15 respectively.

<span><span><span><span>3/4</span>x</span>+11 </span>< <span><span>0.3x</span>+<span>3/4
</span></span></span>First turn 3/4 from both sides to decimals to get..
.75x+11 < 0.3x+.75
And then subtract 0.3x from both sides to get
.45x+11 < .75
And then subtract 11 from both sides to get
.45x < -10.25
And then divide both sides by .45x to get
x < -22.77777778
