1/4*x - 1/6*y= 5 |*18
4/5 *x + 3/8*y = 10 | *8
18/4*x -3*y= 90
32/5*x + 3y = 80
-------------------------
18/4*x+32/5*x / = 170
The answer is a
31) 27
32) 75
33) 74
34) 90 (because it’s a right angle and adds up to 180)
Answer:
Interpreting as: 10y+11=25-3y
Input:
10 y + 11 = 25 - 3 y

Answer:
∠CAB = 28°
∠DAC = 64°
Step-by-step explanation:
What you do in each case is make use of the relationships you know about angles in a triangle and around parallel lines. You can also use the relationships you know about diagonals in a rectangle, and the triangles they create.
<u>Left</u>
Take advantage of the fact that ∆AEB is isosceles, so the angles at A and B in that triangle are the same. If we call that angle measure x, then we have the sum of angles in that triangle is ...
x + x + ∠AEB = 180°
2x = 180° -124° = 56°
x = 28°
The measure of angle CAB is 28°.
__
<u>Right</u>
Sides AD and BC are parallel, so diagonal AC can be considered a transversal. The two angles we're concerned with are alternate interior angles, so are congruent.
∠BCA = ∠DAC = 64°
The measure of angle DAC is 64°.
(Another way to look at this is that triangles BCE and DAE are congruent isosceles triangles, so corresponding angles are congruent.)
Answer:
190 baskets of strawberries
Step-by-step explanation:
The question is incomplete as it didn't state what we are to determine from the information given.
Let's determine total amount picked in the three days.
1st day picked 90strawberries
Amount of strawberries on 2nd day = 2/3 of the amount picked 1st day
= (2/3)(90)
Amount of strawberries on 2nd day = 60 baskets of strawberries
Amount of strawberries picked on 3rd day = (2/3) of the amount picked 2nd day
= (2/3) (60)
Amount of strawberries picked on 3rd day = 40 basket of strawberries
Total amount picked for 3 days = 90+60+40
= 190 baskets of strawberries
