Let's solve your equation step-by-step.

2(x+4)=−5x+1

Step 1: Simplify both sides of the equation.

2(x+4)=−5x+1

(2)(x)+(2)(4)=−5x+1(Distribute)

2x+8=−5x+1

Step 2: Add 5x to both sides.

2x+8+5x=−5x+1+5x

7x+8=1

Step 3: Subtract 8 from both sides.

7x+8−8=1−8

7x=−7

Step 4: Divide both sides by 7.

−7

x=−1

Answer:

x=−1

Y = 7/8u + 9, solve for u

vivado [14]

Answer:

$u=\frac{8y-72}{7}$

Step-by-step explanation:

Flip the equation.

$\frac{7}{8}u+9=y$

Add -9 to both sides

$\frac{7}{8}u+9(-9)=y(-9)$

$\frac{7}{8}u=y-9$

Divide both sides by 7/8

$u=\frac{8y-72}{7}$

Caleb has an assignment to draw a contour map. What type of landform is he most likely drawing?

marysya [2.9K]

The type of land form that Caleb most likely draws is a hill. The answer is option C- a hill.

Step-by-step explanation:

Contour lines are drawn to represent the changes in the elevation which helps to know the slope of the figure drawn.
If the contour lines are drawn close, then steeper the figure is. And more distant the lines are drawn, then less steep the figure is.
Here, the lines seem to be likely circle in shape. The distance of the outermost contour line is 20 ft. The next inner lines will have reduced values of 20 ft.
Therefore, the elevation gets reduced from higher to lower points which provides a diagram of a hill. Since there is no continuous high and low elevations, this cannot be a valley (a range of mountains).
Furthermore, The contour diagram for option A and D such as creek(water stream) or shoreline will have different and mixed values of elevations that seems to be a messy structure of contour lines.

Each marble bag sold by Josh's Marble Company contains 7 yellow marbles for every 5 red marbles. If a bag has 25 red marbles, ho

elixir [45]

5 red : 7 yellow
25 red: ? Yellow

5 x 5 is 25 therefore the multiplier is 5
We multiply 7 by 5 which is 35

Therefore 24 red : 35 yellow

35 yellow marbles
