Solve 3.8 = 2x - 11.2.
X=__
Answer:
x= 15/2 im pretty sure
Step-by-step explanation:
We want to solve the given linear equation, we will find that the solution is x = -3.7
Solving linear equations:
Here we have the equation:
3.8 = 2*x - 11.2
We want to solve this for x, so we can start by subtracting 11.2 in both sides to get:
3.8 - 11.2 = 2*x
-7.4 = 2*x
Now we can divide both sides by 2:
-7.4/2 = x = -3.7
So the solution is x = -3.7

Noah pays $7.65 for a cappuccino on days he's running late to work. One week, he was late on Monday, Wednesday, and Friday. How much did he spend (in $) on cappuccinos that week? $
Answer:
Amount Noah spent on cappuccino for that week = $22.95
Step-by-step explanation:
Noah pays $7.65 for a cappuccino on days he's running late to work
Cost of cappuccino per day = $7.65
One week, he was late on Monday, Wednesday, and Friday.
That is 3 days in a week
How much did he spend (in $) on cappuccinos that week? $
Amount Noah spent on cappuccino = cost of cappuccino per day × 3 days
= $7.65 × 3
= $22.95
Amount spent on cappuccino for that week = $22.95

Triangle PQR is similar to Triangle XYZ. PQ=3 and XY=6. If the perimeter of Triangle XYZ is 20, what is the perimeter of Triangle PQR?
Answer:
10
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
scale factor = [tex]\frac{PQ}{XY}[/tex] = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]
That is the sides of Δ PQR are half those of Δ XYZ, thus
The perimeter of Δ PQR is half Δ XYZ, that is
perimeter of Δ PQR = [tex]\frac{1}{2}[/tex] × 20 = 10
scientific notation for 1.0 ×10^6
Answer:
1000000
Step-by-step explanation:
I'm not sure what you meant by "scientific notation". So uhh, I only solved the 1.0 times 10^6,
10^6=10×10×10×10×10×10
10^6=1000000
(Fun fact. If you ever see a power of 10, you don't actually need to solve it. Look at the power, and add the same amount of 0's. For example 10^2. Power sign is 2. 2 trailing 0's.)

Lines m and n are drawn in the coordinate plane. The equation of line m is y=-3x+8 and line n goes through point (-4,-11). When a transversal of the two lines is constructed the alternate interior angles formed by the transversal are congruent. What is the equation of line n?
Answer:
The equation of line n is;
y = -3x - 23
Step-by-step explanation:
Here, we want to find the equation of line n
For the alternate interior angles to be congruent after drawing the transversal, then both lines must be parallel
If the two lines are parallel, then their slopes are equal
To get the slope of line m, we compare the equation of line m to the standard form
The equation of line m is y = -3x + 8
if we compare this with the standard form which is y = mx + c
Then the slope of line m is -3 and since they are parallel lines, the slope of line n is -3 too
So now, we need to get the equation of line n
It passes through (-4,-11)
What we have already is;
y = -3x + c
we need to get the y-intercept to write the complete equation
To get the y-intercept we simply substitute for (-4,-11)
Thus, we have
-11 = -3(-4) + c
-11 = 12 + c
c = -11-12 = -23
The equation of line n is;
y = -3x - 23
