Answer:
Step-by-step explanation:
to find the original price we will divide the known price by (1-discount)
original price= 84/(1-0.25)=84/0.75=112.00
the lamp was 112
2. They are both straight lines. The solution of a linear system is where the two lines intersect, and if they're both straight lines, then they can only cross once.
See the picture attached.
5y - 16 + 3y + 20 = 180 degrees
Combine like terms on the left side
8y + 4 = 180
Subtract 4 from both sides.
8y = 176
Divide both sides by 8
y = 22
Plug 22 into y for each angle.
3y + 20 = 3(22) + 20 = 66 + 20 = 86 degrees
5y - 16 = 5(22) - 16 = 110 - 16 = 94
The angle opposite 5y - 16 also equals 94 because they are vertical angles.
The angle opposite of 3y + 20 also equals 86 because they are vertical angles
Answer:
(c)- 4/13
Step-by-step explanation:
There are 4 types of cards in a ordinary deck clovers, diamands, hearts, and spades
each set has 1 seven each, so 4 sevens total.
Also, each type of card has 13 different cards in it
so, your answer is 4/13
The new slope is 3, but the y-intercept doesn't change.
