Find the equivalent fraction to next expression 3b^2 + 2(a+5.4b) -2.4b + 1.5a - 2b^2 a 2b2 + 3.5a + 8.4 b b b2 +3.5a + 8.4b c 2b2 + 3.5a + 8.4b d b2 + 10.8a + 8b
Answer:
b²+3.5a+8.4b
Step-by-step explanation:
Given the expression
3b^2 + 2(a+5.4b) -2.4b + 1.5a - 2b^2
Expand
3b^2 + 2a+10.8b -2.4b + 1.5a - 2b^2
Collect the like terms
= 3b²-2b²+2a+1.5a+10.8b-2.4b
= b²+3.5a+8.4b
Hence the equivalent expression is b²+3.5a+8.4b

Answer:
x=68
Step-by-step explanation:
A²+b²=C²
side a:60²=3600
side b:32²=1024
3600+1024=4624
side c=√4624=68
Find the angle measure that of each missing angle
Step-by-step explanation:
122+v=180
v=180-122
v=58
w+61=180
w=180-61
w=119
61+58+y=180
119+y=180
y=180-119
y=61
61+x=180
x=180-61
x=119

What is Trigonometry?The study of triangles' relationships to their angles, lengths, and heights is known as trigonometry. In particular for right-angled triangles, it includes ratios, functions, identities, and formulas to solve issues based on it.
Given:
Base= 30 feet
Angle = 65
Using Trigonometry
tan 65 = P / B
P = B (tan 65)
P = 30 ( tan 65)
or, x= 30 tan 65

bus driver drove from Philadelphia to Washington D.C. He drove the first 100 km in 2 hours, the next 55 km in 1 hour, and the final 75 km in 2 hours. What is the average speed of the bus throughout the trip?
Answer: I think it’s 46
Step-by-step explanation: Because you add up the miles he drove them divide them by how long he drove
Ex 55+75+100=230 then you divide that by 5 hours = 46 per hour
For the line above, what is the slope? *
Answer:

Run = 3
3/3 = 1
Slope = 1
Answer:
1
Step-by-step explanation:
First, you take any two points from the line, I put (2,1) and (0,-1). You plug it into the formula y2-y1/x2-x1 which would be -1-1/0-2 which is equal to -2/-2=1

The reason why the deaths and recoveries occurs so rapidly in the pandemic
Answer:
As time goes by the virus expands, and evolves causing more people to get infected. Although people who have made it before when the virus had affected them do not get affected by the evolved virus. People who have weak immune systems when infected die. Therefore, the reason thatthe deaths and recoveries happen to rappidly is because of the virus evolving, when some people are able to withstand it whilst others die.

Lines s and t are parallel. The slope of line s is −3/2 . What is the slope of line t ?
Parallel lines have the same slopes.
So if line s has a slope of -3/2, line t also has a slope of -3/2.
12 less than 7 times a number, how do I put this in numbers and symbols and letters
Answer:
7x - 12
Step-by-step explanation:
'12 less' means thats u have to subtract 12 from the next number
'7 times a number' means 7 multiplied by a variable like x, y, or z
you put those two together and get 7x - 12
Answer: 7x-12
Step-by-step explanation:
“12 less than” would simply imply “subtract 12 from” the sum of 7 times a number. Let “x” represent the unknown number and multiply it by 7.

Answer:
7.) m = 1/3 ; b = -2.5
8.) m = 2 ; b = 2
Step-by-step explanation:
For m, either do the rise over run method or use 2 points and do (y2-y1)/(x2-x1).
For b, just look at the y-intercept/where it crosses the y axis
I believe those are the right answers but not too sure because the numbers on the graph are a bit blurry so i just assumed it counted by ones.
R(-2,8) S(10,6) midpoint
Answer:
M = (4,7)
Step-by-step explanation:
If points are (x₁,y₁) and (x₂,y₂), then the midpoints are given by :
[tex]M=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})[/tex]
We have,
x₁ = -2, y₁ = 8, x₂ = 10 and y₂ = 6
So,
[tex]M=(\dfrac{-2+10}{2},\dfrac{8+6}{2})\\\\=(\dfrac{8}{2},\dfrac{14}{2})\\\\=(4,7)[/tex]
So, the midpoints of the given points are (4,7).

Answer:
x=29
Step-by-step explanation:
We know for a fact that in a square:
- All of its angles have equal measure (90 degrees)
(e.g. Measure of Angle CAT, measure of Angle CST = 90 degrees)
Now that we know the facts, let's try to find x.
Now since we know that all the angles are equivalent to 90 degrees, we can say that Measurement of Angle SCA is 90 degrees. So:
[tex]90=3x+3[/tex]
Next, we'll simply just isolate the x:
[tex]90=3x+3\\90-3=3x+3-3\\87=3x\\\frac{87=3x}{3} \\29 = x[/tex]
