What value of x makes the equation true?
6x+8=3x-19
A. x = 3
B. x = -3
C. x = -9
D. x = -11/3
Correct answer will get brainiest!
Answers
Answer:
C
Step-by-step explanation:
Given
6x + 8 = 3x - 19 ( subtract 3x from both sides )
3x + 8 = - 19 ( subtract 8 from both sides )
3x = - 27 ( divide both sides by 3 )
x = - 9 → C

Ryan conducted a 6 day study observing the effects of an organic plant food on the growth of his sprouting bean plant. He tracked these two pieces of info:
1. The amount of plant food remaining in the container after each days study.
2. The height of the plant over time.
Ryan found that the amount of plant food remaining decreased an equal amount each day. He used the entire 72 millimeters by the end of his study. Question

0 ≤x ≤6
{0,1,2,3,4,5,6}
{0,6,12,18,24,30}
0 ≤y ≤72
Answers
Answer:
Domain: [tex]0\leq x\leq 6[/tex]
Range: [tex]\{0, 12, 24, 36, 48, 60, 72\}[/tex]
Step-by-step explanation:
Let [tex]y[/tex] or [tex]f(x)[/tex] be equal to the amount of plant food that remains after each day.
[tex]x[/tex] be the number of days that have passed.
Total amount of plant food used is 72 mm.
Number of days the experiment goes on is 6 days.
Plant food used each day is [tex]\dfrac{72}{6}=12\ \text{mm}[/tex].
So, the function will be
[tex]y=f(x)=72-12x[/tex]
at
[tex]x=0,y=72[/tex]
[tex]x=1,y=72-12\times 1=60[/tex]
[tex]x=2,y=72-12\times 2=48[/tex]
[tex]x=3,72-12\times 3=36[/tex]
[tex]x=4,72-12\times 4=24[/tex]
[tex]x=5,72-12\times 5=12[/tex]
[tex]x=6,72-12\times 6=0[/tex]
Value of [tex]x[/tex] is the domain which is [tex]0\leq x\leq 6[/tex].
Value of [tex]y=f(x)[/tex] is the range which is [tex]\{0, 12, 24, 36, 48, 60, 72\}[/tex].

The ratio of girls to boys at soccer practice is 3:4. If on Saturday there will be a total of 42 players, how many boys will be playing and how many girls?
Answers
Answer:
[tex]Boys = 24[/tex]
[tex]Girls = 18[/tex]
Step-by-step explanation:
Given
[tex]G:B= 3:4[/tex]
[tex]Total = 42[/tex]
Required
Determine the number of boys and girls
We have to convert the ratio to fraction;
Number of girls can be calculated as:
[tex]Girls = \frac{G}{G + B} * Total[/tex]
[tex]Girls = \frac{3}{3 + 4} * 42[/tex]
[tex]Girls = \frac{3}{7} * 42[/tex]
[tex]Girls = 3 * 6[/tex]
[tex]Girls = 18[/tex]
[tex]Boys = Total - Girls[/tex]
[tex]Boys = 42 - 18[/tex]
[tex]Boys = 24[/tex]

Which of the following inequalities is equivalent
to -31 + 12s <3s + 15 ?
Answers
Answer:
-31+12s
Step-by-step explanation:
The required inequality that is equivalent to -31 + 12s < 3s + 15 is 9s < 46.
Given that,
To determine the inequalities is equivalent to -31 + 12s <3s + 15.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
-31 + 12s < 3s + 15
12s - 3s < 15 + 31
9s < 46
Thus, the required inequality that is equivalent to -31 + 12s < 3s + 15 is 9s < 46.

A. -2 ≤ x ≤ 5
B. x ≤ -2 OR x ≥ 5
C. x ≤ -15 OR x ≥ 12
D. x ≥ 5
Thank you!
Answers
Answer:
B
Step-by-step explanation:
We have the compound inequality:
[tex]5x+7\leq-3 \text{ or } 3x-4\geq 11[/tex]
Since this is an “OR” inequality, we can solve each inequality individually. So:
1)
We have:
[tex]5x+7\leq-3[/tex]
Subtract 7 from both sides:
[tex]5x\leq -10[/tex]
Divide both sides by 5:
[tex]x\leq-2[/tex]
So, the first solution is above.
2)
We have:
[tex]3x-4\geq 11[/tex]
Add 4 to both sides:
[tex]3x\geq15[/tex]
Divide both side by 3:
[tex]x\geq5[/tex]
Our second solution is above.
Therefore, our solution is:
[tex]x\leq -2 \text{ or } x\geq5[/tex]
Since our original inequality is “OR,” our solution set remains an “OR.”
Hence, our answer is B.

Together teammates Pedro and Ricky got 2689 base hits last season Pedro had 281 more hits than Ricky how many hits does each player have?
Answers
Explanation:
- Let R be the number of hits that Ricky had
- Let P be the number of hits that Pedro had
R + P = 2689
But Pedro has 281 more hit than Ricky
Thus, P = R + 281
Substitute this value in our first equation
R + R + 281 = 2689
2R + 281 = 2689
2R = 2689 - 281
2R = 2408
R = 2408/2
R = 1204
And P = R + 281
But R = 1204
=> P = 1204 + 281 = 1485
Therefore, Pedro has 1485 base hit and Ricky has 1204 hit.
