x= degrees 32° x x
Answer:
32 +x+x=180(Sum of angles of a triangle)
32+2x=180
2x=180-32
2x=148
x=148/2
Therefore,X=74
Answer:
the answer for x is 74°
Step-by-step explanation:
[tex]32 + x + x = 180 \\ 2x + 32 = 180 \\ 2x = 180 - 32 \\ 2x = 148 \\ x = 74 \: degrees[/tex]
If 3/x = 5/y, what is the value of y/x?

Is the equation y=5x+1 a linear equation? Explain.
Answer:
Yes
Step-by-step explanation:
Linear equations are equations in which the highest power of the equation is always 1, they look like a straight line when put on graph and they usually have this form: y = ax + b
y = 5x + 1 is a good example of a linear equation but they may also look like: y = 2x (b = 0) or y = x + 3 (a = 1).

On January 1, one share of stock in the LMNOP Corp was worth $85. By December, it lost 11.6% of its value. What is the new value of one share of LMNOP stock?
Answer:
multiple then dived the numbers together
Based on the previous worth of the stock and the value lost, the new value of the LMNOP stock is $75.14.
What is the new value of the LMNOP stock?The value of $85 lost approximately 11.6% of its value.
The new value can be found as:
= Previous stock price x ( 1 - percentage loss)
Solving gives:
= 85 x (1 - 11.6%
= 85 x 88.4%
= $75.14.

A line passes through the point (6, 7) and has a slope of 4.
Write an equation in slope-intercept form for this line.
Answer:
y = 4x - 17
Step-by-step explanation:
we can use the equation y = mx + b
where m is the slope.
now we want to find the value of b.
so
7 = 24 + b
b= -17
so the answer is
y = 4x -17

What is the solution to this system of equations?
Those equations in the corner are, y = x -4. y = -0.5x + 8
Answer:
x=8, y=4
(8,4)
Step-by-step explanation:
y = x - 4
y = -0.5x + 8
x - 4 = -0.5x + 8
x = -0.5x + 12
1.5x = 12
15x = 120
x = 8

In an arithmetic sequence, T1=4 and T7=22.
Using Simultaneous equations find the values of a and d.
Answer:
Step-by-step explanation:
t1 means a1 and t7 means a7
a+(n-1)d=an
a+(1-1)d=4
so we get a as 4
a=4
a+(n-1)d=an
4+(7-1)d=22
4+6d=22
6d=22-4
d=18/6
d=3
Use the equation n2 n = 56 to determine which figure has 56 blocks. figure has 56 blocks.
The factor of the quadratic equation n² + n = 56 is (n + 8)(n - 7). Then the value of the n is 7 and negative 8.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The quadratic equation will be given below.
n² + n = 56
The equation can be written as
n² + n - 56 = 0
On factorization, we have
n² + n - 56 = 0
n² + 8n - 7n - 56 = 0
(n + 8)(n - 7) = 0
n = 7, -8
The value of the n is 7 and negative 8.
