Answer:
Option A,$320.98 is correct
Step-by-step explanation:
The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.
last balance as shown by the statement was $152.58
new charges were $213.40
payment made by Elijah was $45
new balance=$152.58+$213.40-$45=$320.98
The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.
Congruent sides, so isosceles triangle. When we have an isosceles triangle the bisector of angle A is a perpendicular bisector of BC with foot D. So x=ADB=90 degrees.
Angle B is 47 degrees and angle y=BAD is complementary, the other acute angle in a right triangle.
y = 90 - 47 = 43
Answer: x=90, y=43
Answer:
x ≥ 15
Step-by-step explanation:
First you need to make an equation for this. If he already has $50 and needs <u>at least</u> 500 and deposits $30 per day we can put the equation as 30x + 50 ≥500. The reason we put a greater than or equal sign (≥) rather than the less than or equal sign (≤) is because Fred needs <u>at least</u> meaning you can have exactly or 500 exactly. To solve this you would have to do inverse operation and subtract 50 on both sides. You should have 30x≥450. Then divide 30 on both sides. Your answer should be x ≥ 15.
