Answer:
30° and 150°
Step-by-step explanation:
supplementary means that the sum of the measures = 180
let's say 1 angle is labled ∠A and the other ∠B
m∠A + m∠B = 180°
however, m∠A = 5 * m∠B
so, by substituting that:
5*m∠B + m∠B = 180°
6*m∠B = 180°
m∠B = 30°
m∠A = 150°

5 7\10 × 7 4\16=????? I'm trash with multypliing
9514 1404 393
Answer:
41 13/40
Step-by-step explanation:
Generally, you're told to multiply mixed numbers by converting each to an improper fraction:
5 7/10 = (5·10 +7)/10 = 57/10
7 4/16 = (7·16 +4)/16 = 116/16
The fractions are multiplied by multiplying their numerators to get the numerator of the result, and multiplying their denominators to get the denominator of the result.
[tex](5\frac{7}{10})(7\frac{4}{16})=\dfrac{57}{10}\cdot\dfrac{116}{16}=\dfrac{57\cdot116}{10\cdot16}=\dfrac{6612}{160}\\\\=41+\dfrac{52}{160}=\boxed{41\frac{13}{40}}[/tex]
__
You don't have to mess with reducing the fraction of the result if you reduce the fraction 4/16 to 1/4 to begin with. Then the product is (57/10)(29/4).
_____
Alternate solution
You can also treat this as the product of two sums. The distributive property is handy for this.
(5 + 7/10)(7 + 1/4) = (5)(7) +(5)(1/4) +(7/10)(7) +(7/10)(1/4)
= 35 +5/4 +49/10 +7/40
= 35 +1 +1/4 + 4 + 9/10 + 7/40 . . . . take out the integer parts
= 40 +10/40 +36/40 +7/40 . . . . . . use 40 as a common denominator
= 40 +53/40 = 41 13/40

Write the equation of the line in slope-intercept form that has a slope of 3 and passes through (5, -1)
Answer:
y = 3x - 16
Step-by-step explanation:
In this question, we have to write an equation in slope-intercept form with the given information.
Slope-intercept form: y = mx + b
We already know our slope: 3
However, we don't know what are y-intercept (b) is.
To find this, plug the given information in the equation and solve for b:
-1 = 3(5) + b
-1 = 15 + b
Subtract 15 from both sides.
-16 = b
This means that our y-intercept will be -16.
Now, plug in our new information to the equation:
y = 3x - 16
The equation y = 3x - 16 will be your answer.
Answer:
y = 3x - 16
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Slope: 3
Points: (5, -1)
y = 3x + b
-1 = 3 ( 5 ) + b
-1 = 15 + b
b = -16
y = 3x - 16
CAN SOMEONE SHOW FULL STEPS PLEASEE I BEG YOU ??
Step-by-step explanation:
slope is the number before x so slope here is 3/1 always add the 1 if its a whole number if its a fraction leave it.
y=mx+b
the y-intercept is always be so graphing is now easy
put a dot on the y-intercept so in this case it is 3 on the y-axis. then use rise over run. rise being up and down and run being left and right. so go up 3 then right 1 and put a dot there and connect your 2 lines to make a graph. if the number was -3/1 you go down 3 and right one then but thats just hypothetical
now to make a equation for a point you put it in y=mx+b.

What linear function models the table of values?
Expand and combine like terms.
(4 + 7a²)2 =
Answer:
Step-by-step explanation:
2(4+7a^2)
=8+14a^2
=7a^2+4
OR if that 2 is an exponent
(4+7a^2)^2
=(4+7a^2)(4+7a^2)
=16+49a^4+28a^2+28a^2
=49a^4+56a^2+16

What is -3(2a + 5b - 4y - 2)?
Answer: -6a-15b+12y+6
Step-by-step explanation:
2y-10=6x
plz help me
Answer: simplifying
Step-by-step explanation:
2y + -10 = 6x
Reorder the terms:
-10 + 2y = 6x
Solving
-10 + 2y = 6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + 2y = 10 + 6x
Combine like terms: -10 + 10 = 0
0 + 2y = 10 + 6x
2y = 10 + 6x
Divide each side by '2'.
y = 5 + 3x
Simplifying
y = 5 + 3x

Misha solves the equation 3 x minus 2 (x + 3) = 4 (x minus 2) minus 7 by applying the distributive property to each side of the equation. The result is 3 x minus 2 x minus 6 = 4 x minus 8 minus 7. Misha then wants to combine like terms. Which are the terms Misha should combine? 3x – 2x and –8 – 7 3x – 2x and 8 – 7 3x – 2x + 4x and –6 – 8 – 7 3x – 2x – 6 and 4x – 8 – 7
Step-by-step explanation:
The given equation is : 3x-2(x+3)=4(x-2)-73x−2(x+3)=4(x−2)−7
On solving this equation and applying the distributive property, we have
⇒3x-2x-6=4x-8-73x−2x−6=4x−8−7
⇒x-6=4x-15x−6=4x−15
Combining the like terms like terms consisting of x are solved together and the constants are solved together,
⇒x-4x=-15+6x−4x=−15+6
⇒-3x=-9−3x=−9
⇒x=3x=3
