Answer: 26 feet.
Step-by-step explanation:he
The exercise is not written clearly. Assuming that it asks to find the amount of lumber (in feet) John needs for 3 shelves, let "x" represents that amount of lumber in feet.
Based on the data provided, you know that one shelf requires feet of lumber.
You can convert the Mixed number to Decimal number applying these steps:
1. You must divide the numerator of the fraction by the denominator.
2. You must add the result obtained to the Whole number part.
Then you get:
Knowing this, you can set up the following proportion:
Finally, you must solve for "x" in order to find its value. This is:
Answer:
sure. x=12
Step-by-step explanation:
firstly! we know that the two sections equal 90 degrees (because a right angle is 90 degrees). so, take both of those sections, and put them equal to 90 in an equation.
it would look like this...
(x+42) + (3x) = 90
which is the same as...
<u>x + 42</u> + <u>3x</u> = 90. ignore the parenthesis. they're just for clarification. then we will solve for x!
add similar things together! see x and 3x? those are similar because they have x in them. (HOWEVER! if it's something like x² and x, do not add them together!) x is the same as 1x, by the way. so 1x + 3x. ignore the Xs and add the numbers. it becomes 4x
4x + 42 = 90
move 42 to the other side by minusing it on both parts of the equation!
4x = 90 - 42
4x = 48
divide 48 by 4 so x is alone. there ya go
Remember that all the interior angles of a triangle add up to 180°.
The picture tells us two of the angles,
which is 40° and
which is also 40°.
Subtract the measurement of these two angles from 180° to find the measure of the third angle,
:
180° - 40° - 40° = 100°.
The measure of angle RST is 100°.

Answer: 100°
Answer:
3
Step-by-step explanation:
If you notice the y is the change in distance, so #3 has the best explanation.
