Answer:
6.8 km/hr
Step-by-step explanation:
If Sara ran 34 km in 300 minutes, then, in one hour, she would run
=> 34 : 300
=> ? : 60
=> 300 / 5 : 34 / 5
=> 60 : 6.8
So, if she travels 6.8 km in 60 minutes, her speed is 6.8 km/hr

Which equation has infinitely many solutions?
A. -6.8 + 3y + 2.4 = 4.3 – 3y
B. 1/3y + 2.5 – 2/3y = 1.2
C. 5.1 + 2y + 1.2 = -2 + 2y +8.3
D. 2/5y = 2.3 + 3/2y
Answer:
C
Step-by-step explanation:
5.1 + 2y + 1.2 = -2 + 2y + 8.3 ( subtract 2y on each side)
5.1 + 1.2 = -2 + 8.3 ( collect like terms)
6.3 = 6.3
If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers.
Answer:
C. 5.1 + 2y + 1.2 = -2 + 2y + 8.3
Step-by-step explanation:
-6.8 + 3y + 2.4 = 4.3 - 3y **SOLVE FOR y
-4.4 + 3y = 4.3 - 3y
3y +3y = 4.3 + 4.4
6y = 8.7
8.7 DIVIDED BY 6
y = 1.45 THEREFORE, only one solution
1/3y + 2.5 - 2/3y = 1.2 ** TRANSFORM DECIMALS TO FRACTIONS!
1/3y + 5/2 - 2/3y = 6/5 --> multiply both sides by 30
10y + 75 - 20y = 36 --> collect like terms
-10y = 36 - 75
-10y = -39
y = 3.9 or 39/10 one solution
5.1 + 2y + 1.2 = -2 + 2y + 8.3
5.1 +1.2 = -2 + 8.3 ***2y crosses out as their the same!!
6.3 = 6.3 a REAL solution; infinity many
2/5y = 2.3 + 3/2y
2/5y = 23/10 + 3/2y
4y = 23 + 15y
4y - 15y = 23
-11y = 23
y = -2.09 or -23/11 one solution

Step-by-step explanation:
1) Determine the sign(since there is 2 negatives it turns positive)
Then you simplify the complex fraction to 4/3+3
Then you calculate
2) Determine the signs you get to -6+4/-1+5
calculate -2/4
then solve
3) multiply everything to get 8-(5+(-12))/16+2
Then you calculate 8-(5-12)/18
Calculate again8-(-7)/18

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; m∠p − m∠o = 90 degrees (alternate interior angles)
Answer:
Step 1: It should be m∠m + m∠n + m∠o = 180° (sum of angles in a triangle)
Step-by-step explanation:
He made the mistake in Step 1: m∠m + m∠n + m∠p = 180°
It should be m∠m + m∠n + m∠o = 180°
Then only, he can equate it with m∠o + m∠p in step 3.
So, m∠p is the exterior angle and m∠m and m∠n are the two remote interior angles.
m∠o is the adjacent angle to m∠p. They form a linear pair.
Hence, the correct answer is Step 1.
Correct answer gets brainiest.

Write an equation in standard form of the line that passes through (−6,−10) and has the slope m=1/6.
Step-by-step explanation:
y-b=m(x-a)
y--10=1/6(x--6)
y+10=1/6(x+6)
6y+60=1(x+6)
6y+60=1x+6
6y=1x-54
y=1/6x-54/6
y=1/6x-9
The equation of line is y= 1/6x - 9.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
slope= 1/6
and, passes through (−6,−10)
Now, using slope intercept form
y- a =m (x- b)
y - (-10)= 1/6(x -(-6))
y + 10= 1/6( x + 6)
y + 10 = 1/6x + 1
y= 1/6x - 9
Hence, the equation of line is y= 1/6x - 9.

Answer:
−13.11
Step-by-step explanation:
Simplify the expression.
− 13.11
Answer:
-13.11
Step-by-step explanation:
Remember: Please Excuse My Dear Aunt Sally (PEMDAS)
You use the parentheses first, so it is 18.03-3*(20.76)÷2
So then, you see there are no exponents, so you multiply and divide from left to right. So, 18.03-62.28÷2. Then you divide: 18.03-31.14
Then, you subtract from left to right, which gives you: -13.11
