Enter the number that belongs in D= ?
Answer:
∠ D = 80°
Step-by-step explanation:
Δ BCA and Δ DCE are congruent ( SAS postulate )
Thus corresponding angles are congruent, thus
∠ D = ∠ B
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles in Δ ABC from 180° to find ∠ B
∠ B = 180° - (30 + 70)° = 180° - 100° = 80°, then
∠ D = 80°

what is the parallel slope intercept form pls help?
If the line is parallel to the one given, their slopes are the same, so we need to find the y-intercept, then we can determine the slope-intercept form parallel to the given line.
[tex]-1 = 4(4) + b\\\\-1 = 16 + b\\\\-17 = b[/tex]
Now that we have the y-intercept, we can create the equation.
[tex]y = 4x - 17[/tex]
We can prove this by graphing both lines, like so.

Laqueta has three times as many quarters as Pablo if they each spend $.50 Laqueta will have five times as many quarters as Pablo how many quarters do Laqueta and Pablo have now?
Answer:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = 12
Step-by-step explanation:
Given that:
Laqueta has three times as many quarters as Pablo.
They both spend $0.50.
After that Laqueta will have 5 times as many quarters as Pablo.
To find:
Number of quarters with Laqueta and Pablo now?
Solution:
Let number of quarters with Laqueta = [tex]x[/tex]
Let number of quarters with Pablo = [tex]y[/tex]
As per given statement:
[tex]x=3y ..... (1)[/tex]
In $0.50, there are 2 quarters:
After spending $0.50, number of quarters left with both of them:
Number of quarters left with Laqueta = [tex]x[/tex] - 2 = [tex]3y-2[/tex]
Money left with Pablo = [tex]y[/tex] - 2
As per given statement:
[tex]3y-2 = 5(y-2)\\\Rightarrow 3y-2 = 5y-10\\\Rightarrow 2y = 8\\\Rightarrow y = 4[/tex]
Therefore, the answer is:
Number of quarters with Pablo = 4
Number of quarters with Laqueta = [tex]3 \times 4[/tex] = 12

HELP ASAP
Answer:
The value of x will be:
[tex]x=-5[/tex]Step-by-step explanation:
Given the equation
[tex]4-2(x+7)=3(x+5)[/tex]
Multiply (or distribute) each term in parenthesis on L.H.S by -2, and multiply (or distribute) each term in parenthesis on R.H.S by 3.
[tex]4-2x-14=3x+15[/tex]
simplifying the equation by subtracting 14 from the L.H.S
[tex]-10-2x=3x+15[/tex]
Subtracting 15 from both sides
[tex]-10-2x-15=3x+15-15[/tex]
[tex]-25-2x=3x[/tex]
combining the like terms
[tex]-25=3x+2x[/tex]
[tex]-25=5x[/tex]
dividing both sides of the equation by 5
[tex]\frac{-25}{5}\:=\:\frac{5x}{5}[/tex]
[tex]-5=x[/tex]
Therefore, the value of x will be:
[tex]x=-5[/tex]Henry runs up 10 flights of stairs.
Then, he runs down 10 flights of stairs.
Does this situation represent additive
Inverses? Explain.
Answer:
Yes, it does
Step-by-step explanation:
When we add a number to its additive inverse, the resulting value is zero
The first case is running up 10 flights which we consider positive
then he runs down 10 flights of stairs; this we can consider as - 10
So adding this together, we have -10 + 10 to give zero
What this mean is that we have added a number to its additive inverse

Write the equation of a line through (2,4) and (-6, 8) in any form.
Answer:
Step-by-step explanation:
y=mx+c.... first find m(gradient/slope)
m=Y2-Y1/X2-X1
m=8-4/-6-2
m=4/-8
m=-1/2
Then find c
Take any point and fix in x and y
4=-1/2(2) +c
4=-1 +c
c=4+1=5
Therefore y=-1/2x+5
y+1/2x-5=0
