Solve for x in the figure below
3x-1
21
167°
Answer:
49
Step-by-step explanation:
167 = 21 + (3x - 1)
167 = 20 + 3x
3x = 147
x = 49
Answer is 49
Step-by-step explanation:
167=(3x-1)+21(Exterior angle is equal to two opposite interior angle)
or,167=3x-1+21
or,167=3x+20
or,167-20=3x
or,147=3x
or,x=147/3
or,x=49

Question 1)
Answer:
The slope between (-5, -20) and (9, 9) is:
[tex]m=\frac{29}{14}[/tex]
Step-by-step Explanation
Given the points
(-5, -20)(9, 9)Finding the slope between (-5, -20) and (9, 9)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-5,\:-20\right),\:\left(x_2,\:y_2\right)=\left(9,\:9\right)[/tex]
[tex]m=\frac{9-\left(-20\right)}{9-\left(-5\right)}[/tex]
Refine
[tex]m=\frac{29}{14}[/tex]
Therefore, the slope between (-5, -20) and (9, 9) is:
[tex]m=\frac{29}{14}[/tex]
Question 2
Answer:
the slope between (18, -5) and (18, 20) is undefined.
Step-by-step Explanation
Given the points
(18, -5)(18, 20)As the x-values of the points are the same. It indicates that the given line is vertical.
Finding the slope between (18, -5) and (18, 20)
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [20 - (-5)] / [18 - 18]
= [20+5] / [0]
= 25/0
= ∞ or undefined
Thus, the slope between (18, -5) and (18, 20) is undefined. It indicates that the line is vertical.
Hence, the slope between (18, -5) and (18, 20) is undefined.

4x² + 13 – 2y when x = 3 and y = 8
Answer:
The answer is 33.
Step-by-step explanation:
4x^2 + 13 - 2y, x=3 y=8
In order to evaluate this, you just need to plug the x and y in the expression:
= 4(3)^2 + 13 - 2(8)
= 4(9) + 13 - 16
= 36 + 13 - 16
= 33

Base and height of a parallelogram 12 cm and 8 cm respectively. find its area
please guys give me correct answer
Answer:
96 cm²
Step-by-step explanation:
Area of a parallelogram A = bh where b = base = 12 cm and h = height = 8 cm.
So, A = 12 cm × 8 cm
A = 96 cm²
So, the area of the parallelogram with base 12 cm and height 8 cm is 96 cm².
What is the answer to this ?
Answer:
The answer is option 1.
Step-by-step explanation:
In order to solve x, you have to make x the subject, by multiplying each sides by 5, to get rid of 5 on the left side.
[tex] \frac{x}{5} = 8[/tex]
[tex] \frac{x}{5} \times 5 = 8 \times 5[/tex]

Step-by-step explanation:
Answer:
Could be literally anything.
Step-by-step explanation:
"S" is a variable. All letters can be used, "S" has just been randomly picked. In mathematics, a variable is a symbol which functions as a placeholder for varying expression or quantities, and is often used to represent an arbitrary element of a set. In addition to numbers, variables are commonly used to represent vectors, matrices and functions.

22 = 5(y – 8) please help me
Answer:
y=12.4
Step-by-step explanation:
22/5 is 4.4
so the numbers in the bracket must equal to 4.4
so y is 12.4
Answer:
62/5 or 12 2/5
Step-by-step explanation:
22 = 5(y-8)
22 = 5y - 40
5y−40=22
Add 40 to both sides
5y−40+40=22+40
5y = 22+40
5y=62
Isolate the variable.
5y/5 = 62/5

Please help!! The first time I got this answer I got x≤ 5.25 but i know it's not right.
I know there are smarties out there. Please help!!
Answer:
lol
Step-by-step explanation:
Yeah i have no clue but good luck
[tex]-3-4x\leq 21 \\~\\-3-4x+3\leq 21+3 \\~\\-4x \leq 24[/tex]
When you multiply both sides by a negative number, you have to flip the inequality.
[tex]-4x\cdot \left(-\dfrac{1}{4}\right) \geq24\cdot \left(-\dfrac{1}{4}\right) \\~\\x \geq-6[/tex]
You could also solve by doing this:
[tex]-4x \leq 24 \\~\\-4x +(4x-24) \leq 24 +(4x-24) \\~\\-24 \leq 4x \\~\\-6\leq x[/tex]
If -6 is less than or equal to x, then x is greather than or equal to -6.
Mr. Cruz fills a 3-gallon water cooler for a family picnic. He brings plastic cups that each hold 12 fluid ounces of water. How many plastic cups can Mr. Cruz completely fill with the water from the cooler?
One gallon is equivalent to 128 fluid ounces
3 gallons is equivalent to 3*128 fluid ounces
= 384 fluid ounces
One plastic cup can hold 12 guide ounces
So cups needed will be 384/12
32 cups
Mr. Cruz can completely fill 32 plastic cups with the water from the cooler.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
The 3-gallon water cooler contains 3 x 128 = 384 fluid ounces of water.
We can divide the total amount of water in the cooler by the amount of water each plastic cup can hold to find out how many cups can be completely filled:
384 fluid ounces / 12 fluid ounces/cup = 32 cups
Therefore, he can completely fill 32 plastic cups with the water from the cooler.

Simplify the following expression
-5(6 - 2i) +(3+ i)(2-3i)
evaluate sinB given that sinA=-1, a=10 and b=4
Answer:
-2.5
Step-by-step explanation:
Using the sine rule, a/sinA = b/sinB.
So, sinB = bsinA/a
substituting sinA = -1, a = 10 and b = 4, we have
sinB = 10 × (-1)/4
= -10/4
= -5/2
= -2.5
Solve for the hypotenuse in the right triangle shown
Answer:
C.) Square root of 34
Step-by-step explanation:
a^2 + b^2 = c^2
3^2 + 5^2 = c^2
9 + 25 = c^2
c^2 = 25 + 9
c^2 = 34
√c^2 = √34
A straight-line graph
• has gradient 4
• crosses the y axis at (0, −3).
Write down the equation of the graph.
Given:
A straight-line graph has gradient 4 and crosses the y axis at (0, −3).
To find:
The equation of the given graph.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(i)
Where, m is the slope of the line and b is the y-intercept.
A straight-line graph has gradient 4. It means the slope of the line is 4.
[tex]m=4[/tex]
Line crosses the y axis at (0, −3). So, y-intercept is -3.
[tex]b=-3[/tex]
Putting m=4 and b=-3 in (i), we get
[tex]y=(4)x+(-3)[/tex]
[tex]y=4x-3[/tex]
Therefore, the equation of the given line graph is [tex]y=4x-3[/tex].
Renee calculated 3/6 plus 2/4 and said the answer equaled 5/10. Amanda solved the same problem and said the answer equaled one whole. Whose answer is more reasonable?
Answer:
Amanda's
Step-by-step explanation:
Given :
3/6 + 2/4
The L. C. M of 6 and 4 = 12
(6 + 6) / 12
12 / 12
= 1
Renne's result = 5/10
Amanda's result = 1 whole
Hence, Amanda's result makes more sense.
