Answer:
a=32b=80Step-by-step explanation:
Find values of a and b that make both equalities true:
a/b = 2/5 and 22/a = 11/6 .
given that 22/a=11/16
cross multiply
11a=22x16
11a=352
a=352/11
a=32
put a=32 in a/b = 2/5 to find b we have
32/b=2/5
cross multiply we have
2b=32x5
2b=160
divide both sides by 2 we have
b=160/2
b=80
Answer:
Step-by-step explanation:
First, we will start by solving: 22/a = 11/6
Solving for a
We can first cross multiply and we get this: 22 x 6 = 11a, Simplified it would be 132 = 11a. Now we know that a = 12.
Solving for b
Now knowing a = 12 we can get this. 12/b = 2/5 same thing, cross multiply. That would be: 12 x 5 = b x 2, Simplified: 60 = 2b so b = 30

Solve the following equation: *
3(2x - 5) = 9x + 24
Enter your math answer
Answer:
4. x = 11
5. x = -13
Step-by-step explanation:
4. 3x + 7 = 5x - 15
-7 -7
3x = 5x - 22
-5x -5x
-2x = -22
-2x/-2 = -22/-2
x = 11
5. 3(2x - 5) = 9x + 24
6x - 15 = 9x + 24
+15 +15
6x = 9x + 39
-9x -9x
-3x = 39
-3x/-3 = 39/-3
x = -13

Find the value of a. Then find the angle measures of the quadrilateral.
Answer:
a = 60
Step-by-step explanation:
Since it is a quadrilateral, the sum of interior angles is equal to 360°. Now you have to create an equation to solve this question. To create an equation, you have to add all the interior angles to 360°.
The equation would be 2a°+a°+a°+2a° = 360°.
Then you would simplify it to 6a° = 360.
You would divide 6 on both sides to get to a° = 60.
Therefore, the value of a is 60.

38 A.
1. BCD
2. ZECF
3. ZDCF
Answer/Step-by-step explanation:
1. <ABC and <BCD are alternate interior angles. Alternate interior angles are equal, therefore, since m<ABC = 38°, then m<BCD = 38°
2. m<ECF = m<BCD (corresponding angles)
m<ECF = 38° (substitution)
3. m<DCF + m<ECF = 180° (linear pair)
m<DCF + 38° = 180° (substitution)
m<DCF = 180° - 38° (Subtraction property of equality)
m<DCF = 142°

Answer:
x=2
Step-by-step explanation:
hope it helps
please mark as Brainliest
Answer:
x = 2
Step-by-step explanation:
For me it's easier to work with decimals than fractions, so I converted 3/4 to .75
.75(x + 18) = 15
.75x + 13.5 = 15
That was just distributing the .75 but here is where it gets a bit confusing.
.75x + 13.5 = 15
-13.5 -13.5
.75x = 1.5
Divide both sides by .75 to isolate the variable.
x = 2

Answer:
equation: 3x - 2 + 4x - 9 + 3x - 9 = 180 x = 20Step-by-step explanation:
add all internal angles
∠H + ∠I + ∠J = 180
equation: 3x - 2 + 4x - 9 + 3x - 9 = 180
combine similar terms: 3x + 3x + 4x = 180 + 2 + 9 + 9
simplify: 10x = 200
divide 10 both sides: x = 20

Selecting a State Choose one of the 50 states at
random.
a. What is the probability that it begins with M?
b. What is the probability that it doesn't begin with a
vowel?
Answer:
PART ONE- 8/50 PART 2-38/50
Step-by-step explanation:
First of all, we know that there are 50 states. Lets see how many states begins with M first.
Maine (27 C, 5 P)
Maryland (28 C, 5 P)
Massachusetts (29 C, 4 P)
Michigan (28 C, 4 P)
Minnesota (28 C, 2 P)
Mississippi (27 C, 6 P)
Missouri (25 C, 3 P)
Montana (27 C, 6 P)
There are 8 states which means that the probabilty is 8/50 which simplifies to 4/25
We know that 12 states begins with a vowel. 50-12 is 38/50
The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.
Given that, Selecting a State, Choose one of the 50 states at random.
We know that, P(A) = n(A)/n(S)
where, P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.
a) There are 8 states which begins with M, that means the probability = 8/50 = 4/25 = 0.16
b) We know that 12 states begins with a vowel,
Therefore, the probability that it doesn't begin with a vowel = 1 - 12/50 = 38/50 = 0.76
Hence, The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76

What is the slope intercept form for this?
Slope= -1 Y intercept= 8
Answer:
y= -x+8
Step-by-step explanation:
y=m+b Replaced M with -1 which will be -x.
y= -x+b Then replace the b with 8.
y= -x+8
You do -x because its the same as -1.
Answer:
y = -x + 8
Step-by-step explanation:
Hi there!
We are given that the slope of a line is -1 and the y intercept of that same line is 8
We want to find the equation in slope-intercept form
Slope-intercept form can be written as y=mx+b, where m is the slope and b is the y intercept
As we are already given the values of the slope and the y intercept, we can simply substitute these values into the formula to find the equation.
First, substitute -1 as m in the equation:
y=-x+b (when 1 is the coefficient, you don't need to write '1' in front of a variable; when -1 is the coefficient, putting only a - sign will suffice)
Now substitute 8 as b in the equation
y = -x + 8
Hope this helps!

A deal is a deal, so here is a good one, let's see who gets it right I had $5.00. My mom gives me $10.00, My dad gave me $30.00. My aunt and uncle give $100.00. I had another $5.00. How much money did I have?
Answer:150.00$
Step-by-step explanation:
The total amount that the person will have is $150.00
Amount that the person had = $5.00 + $5.00 = $10.00Amount given by mum = $10.00Amount given by dad = $30.00Amount given by aunt and uncle = $100.00The total amount that the person had will be the addition of all the amount that he already had and those that he was given. This will be calculated thus:
$10.00 + $10.00 + $30.00 + $100.00 = $150.00
Therefore, the total amount that the person will have is $150.00
