3x+1/10=x-1/7
subtract 1/10 from both sides
3x=-1/7-1/10+x
subtract x from both sides
2x=-1/7-1/10
add -1/7 and -1/0
1/7=10/70
1/10=7/70
-10/70-7/70=-17/70
2x=-17/70
divide by 2 ro multiply by 1/2
x=-17/140
Answer:
Julia found 5 coins
Step-by-step explanation:
lets take the # of coins julia found as "x"
alice found6
davi found 5
lucas found 6
and carter found 8
remember how to calculate mean( add all numbers and divide by the# of numbers)
so
6+5+6+8+x/5=6 (since there are "5" terms)
so
25+x/5=6
treat this like a linear equation so multiply by 5 on both sides
25+x/5(5)=6(5)
25+x=30
subtract "25 on both sides"
25-25+x=30-25
x=5
hope this helps
Answer: 4×15= 60
Step-by-step explanation:
60 is 15 times as many as 4. This means that 15 is multiplied by 4 to get 60. This will be :
4×15= 60.
The other options such as 60÷15=4, 15+4= 60, 60÷4=15 and 60-15= 4 doesn't explain the question given. 60-15 is not 4 likewise 15+4 isn't 60. For the other options, the question isn't talking about division but multiplication.
Equation is y = -1/6x
Step-by-step explanation:
- Step 1: Given that slope, m = -1/6 and a coordinate (12,-2). Write the equation and find the y-intercept, b.
⇒ y = mx + b
⇒ -2 = -1/6 × 12 + b
⇒ -2 = -2 + b
∴ b = 0
- Step 2: Write the equation in slope intercept form.
⇒ y = -1/6x + 0
⇒ y = -1/6x
We conclude that the slope of the linear equation that passes through the points (9, 1) and (10, -1) is -2.
<h3>
How to get the slope of the line that passes through the points (9, 1) and (10, - 1)?</h3>
A linear equation has the general form:
y = a*x + b
Where a is the slope of the line, and b is the y-intercept.
There is a simple equation to get the slope of a point if we know two points. For a line that passes through ( a, b) and (c, d), the equation for the slope is:
a = (d - b)/(c - a)
In this case we know that our line passes through (9, 1) and (10, -1), then using the above equation, we can see that the slope is:
a = (-1 - 1)/(10 - 9) = -2
We conclude that the slope of the linear equation that passes through the points (9, 1) and (10, -1) is -2.
