3x9=27
21/3 = 7
so
7+27x9+5
27x9=243
243+7+5
answer is 255
For numbers 15-17, we need to remember that two of a triangle's angles are always acute and the third angle will allow us to classify the triangle based on its angles. now that we know this, let's look at #15. the first two angles listed are acute, and the third is an obtuse angle, therefore it is an obtuse triangle. on #16 we have three acute angles, so it is an acute triangle. #17 has two acute angles and a right angle so it is a right triangle.
on numbers 21-23, we need to know that a triangle with all congruent sides is called equilateral, a triangle with two equal sides is isosceles, and a triangle with no equal sides is called scalene. #21 shows two equal sides so it is an isosceles triangle. #22 has three equal sides so it is an equilateral triangle. #23 has no equal sides so it is scalene. hope this helped! :)
Answer:
y=-5/2+x
Step-by-step explanation:
Answer:
The Equation is
4x+2y= 200
Then total number of candy bars is
X+Y
Step-by-step explanation:
Shelby made $200 from selling x at $4 each and y at $2 each.
Let's have in mind that x is the number of large candy bars
And y is the number of small candy bars
The equation is simple
The amount it was sold is going to be the coefficient of the numbers we don't Know...
So
Equation is
4x+2y= 200
Then total number of candy bars is
X+Y
