Answer:
x = 19
Step-by-step explanation:
(5x + 4)° + (x - 2)° + (3x + 7)° = 180°
(5x + x + 3x)° + (4 - 2 + 7)° = 180°
9x° + 9° = 180° → ÷9
x + 1 = 20

joes dad weighs 140 pounds more than joe. their combined is 336 pounds. how much does his dad weigh?
Answer: 238 lbs
Step-by-step explanation:
x = joe's weight
y = joe's dad's weight
x + y = 336
y = x +140
Substitute for y
x + x + 140 = 336
2x + 140 =336
2x = 196
x = 98
Joe weighs 98 lbs
Now, plug that into Joe's dad's weight equation
y = 98 + 140
y = 238
Joe's dad weighs 238 lbs

Tristan is building steps up to a deck that is 156 yards above the ground. The steps must all be the same height. If he wants to make 8 steps, how high should he make each step?
Answer:
The height of each step is 1957 yards
Step-by-step explanation:
we are given
Tristan is building steps up to a deck that is 15656 yards above the ground
so, total height =15656 yards
Number of steps =8
now, we can use formula
Height of each step = ( total height)/( number of steps)
now, we can plug these values
and we get

Write 3 other expressions that are equivalent to 8x-12
To write equivalent expressions, we multiply all the quantites by the same number.
8x - 12 = ( 2 x 8x) - (2 x 12) = 16x - 24
Using the same method, you can write 3 equivalent expressions :
16x - 24 ; 24x - 36 ; 32x - 48

What would need to be added to
complete the square ?
Answer:
add 6 unit tiles
Step-by-step explanation:
The square is completed when the algebra tile grid pattern is a square. This one will be a square when 6 more unit tiles are added to fill the empty spaces at the bottom right.
We need to add 6 to complete squares.
What must be added to complete the square?
Here we have the expression:
x^2 + 8x + 10
By looking at the image, we can see that we need to add 6 cubes of the ones with the digit 1.
That is equivalent to adding 6 to our expression (and we also subtract 6 so we don't change it) then we have:
x^2 + 8x + 10 + 6 - 6
(x^2 + 8x + 10 + 6) - 6
(x^2 + 8x + 16) - 6
(x^2 + 2*4*x + 4^2) - 6
(x + 4)^2 - 6
So we completed squares, then we conclude that we need to add 6 to complete squares.

Find the measure of angle A.(First solve for x, then plug it into 9x+4 to get the final answer!)
Answer:
40 degrees
Step-by-step explanation:
Sum of all angles of triangle is 180 degrees.
So, 80+(9x+4)+(16x-4)=180
80+25x=180
25x=100 -> x=4
So angle A = 9(4)+4= 40 degrees
The measure of angle 1 is 102°.
What is the measure of angle 2?
Answer:
Step-by-step explanation:
∠1 & ∠2 are co interior angles. co interior angles are supplementary.
∠1 + ∠2 = 180
102 + ∠2 = 180
∠2 = 180 - 102
∠2 = 78°
How many triangles can be formed with segments measuring 4. 72 yd, 6. 31 yd, and 1. 67 yd? none one more than one.
The triangle inequality theorem is not followed, no triangle can be formed.
TrianglesIn Geometry, a triangle is a three-sided polygon that consists of three edges and three vertices.
The triangle inequality theorem describes the relationship between the three sides of a triangle.
According to the triangle inequality theorem, the sum of any two sides must be greater or equal than the length of the third side.
Here, the sides are 4.72 yds, 6.31 yds, and 1.67 yds.
4.72 + 6.31 = 11.02 > 1.67 (theorem followed)
4.72 + 1.67 = 6.39 > 6.31 (theorem followed)
6.31 + 1.67 = 7.98 > 4.72 (theorem not followed)
Since the triangle inequality theorem is not followed,
Hence, no triangle can be formed.

Brad ordered 6 equal-priced items. If the shipping cost was $7 and he paid a total of $37, how much did each item cost? Write and solve an equation to answer the question, and then identify the statement that is not true.
Answer:
B gives you the equation, A is wrong
Step-by-step explanation:
We have this information: 6 items, $37 total, and shipping cost $7.We know that we would have to divide $30 by 6 to get the cost for each item, and add $7 to get $37.Each item would cost $5.With this information, we know that C and D are true.Using the information we have (6 being the divisor and 37 being the total) we know that B is not wrong.

(d) Find the equation of the axis of symmetry.
equation of axis of symmetry: 1
The graphs of parabolas are used to represent quadratic functions and equations
The direction of the parabolaFrom the graph, we can see that the graph of the parabola opens downward
The interceptsThe graph crosses the x-axis at x = 2, and it crosses the y-axis at y = -4
So, the x-intercept is x = 2, and the y-intercept at y = -4
The vertexThis is the maximum point on the graph.
So, the coordinate of the vertex is (2,0)
The equation of the parabolaA parabola is represented as:
[tex]y = a(x - h)^2 + k[/tex]
The parabola opens downward.
So, we have:
[tex]y = -1(x - h)^2 + k[/tex]
The vertex is (2,0).
So, we have:
[tex]y = -1(x - 2)^2 + 0[/tex]
[tex]y = -(x - 2)^2[/tex]
Hence, the equation of the parabola is [tex]y = -(x - 2)^2[/tex]
