Answer:
7 x 4
Step-by-step explanation:
Let the width be x, length will be 3x-5. ATQ, x(3x-5)=28. x=4 and x=-7/3, since length isn't negative, x=4. Width=4 and length=7
Answer:
Step-by-step explanation:
let price of one pretzel=x
price of one soda=y
3x+4y=11.25 ...(1)
5x+2y=8.25 ...(2)
multiply by 2
10x+4y=16.50 ...(3)
(3)-(1) gives
7x=5.25
x=0.75
from (1)
3(0.75)+4y=11.25
2.25+4y=11.25
4y=11.25-2.25
4y=9
y=9/4=2.25
cost of one pretzel=$0.75
cost of one soda=$2.25
Answer and Step-by-step explanation:
H.o../.m//oz.y.g.o.u.s. m.e.a.n.s. .t.h.e. a.l.l.e.l.e.s. .o.f .a. .g.e.n.e. .or. .g.e.n.e.s. are identical for a trait.
He/t//erozygous means the a.l.l.e.l.e.s of a g.e.n.e or .g.e.n.e.s. are not identical for a t.r.a.i.t., meaning that they have a recessive g.e.n.e along with a d.o.m.i.na.n.t g.e.n.e.
When we combine the H.o.m././.o.z.y.g.o.u.s .d.o.m.i.n.a.nt P.ur.p.l.e. .F.l.o.we.r. <em>F//F</em> with the h.o//.m./o.z.y.g.o.us. re.c.e.s.s.i.v.e. .w.h.i.t.e. .p.l.an.t <em>f//f</em>, the result is that all of the offspring will be purple in appearance, meaning that the number of offspring that will be purple is <u>D. 4.</u>

Answer:
40
Step-by-step explanation:
LCM
multiples of 5: 5, 10, 15, 20, 25, 30, 35, <u>40</u>
multiples of 8: 8, 16, 24, 32, <u>40</u>
<u />
the least (smallest) number that is a multiple of both 5 and 8 is 40
