Step-by-step explanation:
Fill in the numbers: It's the 100s chart cut into pieces. You are looking for numbers that are 1 less, 1 more, 10 less or 10 more than a number.
1.679 kg * (40 min)/(kg) + 20 min = 67.16 min + 20 min = 87.16 min
Answer:
Step-by-step explanation:
Let f(x) be the polynomial function of minimum degree with real coefficients whose zeros are 5, -3, and -1 + 3i be f(x).
By the complex conjugate property of polynomials, -1-3i is also a root of this polynomial.
Therefore the polynomial in factored form is 
We expand to get:
We expand further to get:\
Answer:
First account= 2500
Second account= 4000
Step-by-step explanation:
Total amount invested: 6500
Amount in first account: x
Amount in second account: y
x+y=6500
1.13x+0.9y=6500-75=6425
You have two equation now just solve the system of equation through either substitution or elimination.
Then you'll get the answer
x= 2500
y= 4000
Answer:
Tamara incorrectly factored the whole expression.
Step-by-step explanation:
Note that
- 21x=3·7·x;
- 56xy=2·2·2·7·x·y.
Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.
Thus,
21x+56xy=7x(3+8y).
Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.
