2(2x+8)+9=37
1.) the solution is x=3
2.)subtract 25 from both sides
3.) multiply 2 by 2x and 8
4.) add the like terms on the left hand side to get 25
5.) divided by 4 on both sides
Answer:
2(2x+8)+9=37
4x+16+9=37
4x+25=37
4x=37‐25
4x=12
x=12/4
x=3
Answer:‐ (1)
The solution is x = 3
In ΔIJK, k = 64 inches, j = 17 inches and ∠J=68°. Find all possible values of ∠K, to the nearest 10th of a degree.
Answer:
N/A (if on delta math leave blank)
Step-by-step explanation:
(3.4905745)=ERROR
Sine cannot be greater than 1.
The given conditions cannot form a triangle, there is no possible value of K.
What is sine law?In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
Given that, in a triangle Δ IJK, k = 64 inches, j = 17 inches and ∠J = 68°.
We need to find value of ∠K,
So, using the sine law,
Sin K / k = Sin J / j = Sin I /i
So,
Sin K / k = Sin J / j
Sin K / 64 = Sin 68° / 17
Sin K = 3.5
K = Sin⁻¹(3.5)
K = ERROR
Hence, the given conditions cannot form a triangle, there is no possible value of K.

Find the slope and y-intercept for the equation that passes through
these two points.
(2, 5) and m = 3
i need help on this question(2,5) and m=3 slope and y-intercept
Answer:
The slope is 3 and the y-intercept is -1.
Step-by-step explanation:
y-y1=m(x-x1)
y-5=3(x-2)
y=3x-6+5
y=3x-1
y=mx+b where m=slope and b=y-intercept.
Write an equation in slope-intercept form from the given information.
The slope is 3 and the line passes through the point (5, 16).
One day 197 Eagle Ridge students went on a field trip. Five busses were filled with the same number of students, and two students traveled separately by car. How many students were on each bus?
Answer: 39 students
Step-by-step explanation:
First, remove the number of students who traveled by car from the total number so we can see the number of students who traveled by bus:
= 197 - 2
= 195 students by bus.
These 195 students traveled in 5 buses. The number of students on each bus is therefore:
= No. of students traveling by bus / No. of buses
= 195 / 5
= 39 students

find MK
Answer:
MK=32.5
Step-by-step explanation:
Hey There!
I believe that these triangles are similar
So to find MK we want to find the scale factor
To do this we divide
66/30=2.2
Now we want to divide 72.5 by 2.2
72.5/2.2=32.5
therefore MK=32.5
