What is the value of m in the equation 5m − 7 = 6m 11? 18 1 −18 −1.
Answer:
-7 = m
Step-by-step explanation:
5m − 7 = 6m
Subtract 5m from each side
5m-5m − 7 = 6m-5m
-7 = m

What is the length of bd
Answer:
B
Step-by-step explanation:
I would use the Pythagorean theorem to solve distances between 2 points, and this case is no exception.
We need to find the positive difference in their x coordinates and y coordinates.
The difference in x coordinates: 7
The difference in y coordinates: 8
Now we can use the Pythagorean theorem:
7^2+8^2 = x^2
49+64 = x^2
113 = x^2
x = sqrt(113)
Therefore, the answer is B.
A profit of Rs. 30,000 is to be distributed among A, B and C in
the proportion 3:5:7 respectively. What will be the difference
between B's and C's amount?
Answer:
4000
Step-by-step explanation:
Split in a ratio of 15.
30000/15 = 2000
7x2000 - 5x2000 = 4000
4000
Answer:
4000
Step-by-step explanation:
A:B:C=3:4:7
And profit =30,000
(A+B+C)*x=3+5+7=15x
And then 15X=30,000
X=2000
Know difference between B and C
(B-C)x=7-5=2
Know difference between B and c is

Ans 4000
Write an equation of a line that passes through the point (0,-2) and is perpendicular to the image shown.
options:
y= 3x −2
y= −1/3x − 2
y= 1/3x
y= 3x − 10
Answer:
Brainliest Answer would be appreciated. Option 1 is the best
Step-by-step explanation:
The slope of the line on the graph is -1/3. A perpendicular line's slope is always the negative reciprocal of it, so your slope of the perpendicular line would be 3.
Also, since you are passing through the point (0, -2), -2 would be your y-intercept, making your equation for the perpendicular line y = 3x - 2.

find the simple intrest on rs 1200 at 5%per annum for 2 years
Answer:
Rs.120
Step-by-step explanation:
given,
Principal (P) = Rs.1200
Time (T) = 2 yrs
Rate (R) = 5%
Simple interest = ?
solution,
simple interest = PTR/100
= Rs.1200*2*5/100
= Rs.12000/100
= Rs.120
Therefore,the simple interest is Rs.120.
In your own words, explain why when we multiply terms that have the same bases, we add the exponents.
When multiplying exponents, remember the first rule: when multiplying similar bases, add powers together. 52% + 56% =? The bases of the equation remain unchanged, while the exponents' values are added together. Adding the exponents is only a quick way to get at the answer. Simply add the exponents to multiply exponential expressions with the same base. Simplify. The product rule applies because the base of both exponents is a. With a common basis, add the exponents.

Which of the following is the measure of the largest angle in the triangle shown?
19x + 7x + 10x = 180°
36x = 180
x = 5°
largest angle = 19 * 5 = 95°
Answer:
C. 95°
Step-by-step explanation:
19x+ 7x +10x = 180 (sum of the interior angles of a triangle is 180)
36x = 180
x= 180÷36
x= 5
Magnitude of the largest angle
= 19× x
= 19× 5
= 95
Define operation $\heartsuit$ so that \[ a \heartsuit b = \dfrac{a + b}{2}. \] Let $H$ be a function defined by \[H(x,y,z) = \left(x \heartsuit y\right) \heartsuit z - x \heartsuit \left(y \heartsuit z\right). \] Write an expression for a simplified version of this function: $H(x,y,z) = \boxed{\phantom{blaaaaaaaaaa^2_2}}$ Write an expression, not an equation. Sample answer: $x + y + z$
Answer:
(-x+z)/4
Step-by-step explanation:
Evaluate the $\heartsuit$ operation to simplify.
\begin{align*}
H(x,y,z) &= \left(x \heartsuit y\right) \heartsuit z - x \heartsuit \left(y \heartsuit z\right) \\
&= \left(\dfrac{x+y}{2}\right) \heartsuit z - x \heartsuit \left(\dfrac{y+z} 2\right) \\
&= \dfrac{\dfrac{x+y}{2} + z}{2} - \dfrac{x + \dfrac{y+z}{2}}{2}
\end{align*}This looks ugly, but it works out! Continue by multiplying each fraction's numerator and denominator by $2$, in order to eliminate the complex fractions.
\begin{align*}
H(x,y,z) &= \dfrac{\dfrac{x+y}{2} + z}{2} - \dfrac{x + \dfrac{y+z}{2}}{2} \\
&= \dfrac{x + y + 2z}{4} - \dfrac{2x + y + z}{4} \\
&= \dfrac{(x+y+2z) - (2x + y + z)}{4}
&= \dfrac{-x+z}{4}
\end{align*}Surprisingly it simplifies all the way down to $H(x,y,z) = \boxed{\dfrac{-x + z}{4}}$. The value of $y$ is not even used!

The base angles are equivalent.This means that:
This triangle is an isosceles triangle.The legs of the triangle are equivalent.Let's use Pythagoras theorem to find z.
Finding z using Pythagoras theorem.
[tex](8\sqrt{x} )^{2} = z^{2} + z^{2}[/tex]⇒ [tex](8\sqrt{x} )( 8\sqrt{x} ) = 2z^{2}[/tex]⇒ [tex](8)(8)(2)= 2z^{2}[/tex]⇒ [tex](8)(8)= z^{2}[/tex]⇒ [tex]64= z^{2}[/tex]⇒ [tex]\sqrt{64} = \sqrt{z^{2}}[/tex]⇒ [tex]8 = z[/tex]Thus, the value of z is 8.
q-10=6(r+1)
rearrange the equation so r is the independent variable
Answer:
r = (q-16)/6
Step-by-step explanation:
q-10 = 6(r+1)
q-10 = 6r+6
q-10-6 = 6r
q-16 = 6r
r = (q-16)/6
Hunter kicked a soccer ball. The ball went 332 yards in 38 second. At that rate, how far would the ball go in 1 second?
The distance that he would the ball go in 1 second will be 8.8 yards.
How to calculate the rate?From the information, Hunter kicked a soccer ball. The ball went 332 yards in 38 second.
Therefore, at that rate, the distance that he would the ball go in 1 second will be:
= Total distance / Time
= 332 / 38
= 8.8 yards.

Can you find the PERIMETER of this shape pls
Answer:
25.7 m
Step-by-step explanation:
Hello!
We have two sides each measuring 5m, so the length of the straight edges is 2(5m) or 10m
We also have two identical semi-circle circumferences, so if we find the circumference of the whole circle, we can find the total length of the curved edges.
C = 2πrC = 2(3.14)(2.5)C = 5(3.14)C = 15.7Now, we can add up the two lengths:
Perimeter = straight sides + curved sidesPerimeter = 10m + 15.7mPerimeter = 25.7mSlope of x 15 17 19 21 y -10 2 14 26
